The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

which contain only single covalent bonds.
• General formula for straight chain of alkanes
is CnH2n+2 where n≥1
• Each carbon atom is alkanes is
sp3 hybridised
tetrahedral with four sigma bond (formed
by the four sp3 hybrid orbitals)

5. • Starting from C4H10 onwards, the
alkanes show the phenomenon of chain
isomerism
• They can exist as linear or branched
alkanes.
8. STEP 1
• Choose the longest continuous chain of carbon
atoms; this chain determines the parent name
for alkanes.
9. STEP 2
• Number the longest chain beginning with the
end of the chain nearer the substituent.
10. STEP 3
• Use rule number 2 to locate the position of the
substituent.
• The position and the name of the substituent
must be written in front of the parent chain.
11. STEP 4
–If two or more substituent are
present, give each substituent a number
corresponding to its location on the longest
chain.
The substituent should be listed alphabetically
In alphabetizing, the prefixes di, tri, tetra, sec-, tert-
are ignored except iso and neo
12. STEP 5
• If two substituent are present on
the same carbon atom, use that
number twice.
13. STEP 6
• If two or more identical substituent are
present, use prefixes di-(two identical
substituent), tri-(three identical
substituent), tetra-(four identical
substituent).
• Commas are used to separate numbers
from each other.
14. STEP 7
• If there are two chains of equal
length as the parent chain, choose
the chain with the greater
number of substituent.
15. STEP 8
• If branching occurs at an equal distance
from either end of the longest
chain, choose the name that gives the
lower number at the first point of
difference.
17. Introduction
Called as naphthenes
Types of alkanes that have one or more
rings of carbon atoms
Contain only carbon-carbon single bonds
and are saturated hydrocarbons.
General formula : CnH2n.
Has less hydrogen atom than alkanes
Drawn in simple polygons
18. Continue..
Each corner of polygon is a carbon atom attached
to two hydrogen atoms.
The single ring are named analogously to their
normal alkanes counterpart of the same carbon
count such as
Cyclopropane, Cyclobutane, Cyclopentane,
20. Continue..
One carbon atom shared between two rings
known as spiro cyclic compounds. Fused ring
compounds shared two common atoms and
the bond between them. Bridged ring
compound shared two nonadjacent carbon
atoms.
21. Naming Cycloalkanes
Cycloalkanes are named according to
the IUPAC system by using the prefix
cyclo-.
There are only two steps:
1) Find the parent.
2)Number of substituent and write the
name.
22. Step 1:
Find the parent
Count the number of carbon atoms in the
ring and the number in the largest
substituent
If the number of carbon atoms in the
ring greater or equal to substituent, it is
called alkyl-substituent
If the number of carbon atom in the
largest substituent is greater than the
number in the ring, it named as a
cycloalkyl-substituted alkane.
23. Step 2:
Number of Substituent and
Write The Name
For alkyl or halo-substituent(i)
• If two or more substituents, choose a point of attachment as
carbon 1 such that the second substituent has a low number
as possible
For different alkyl(ii)
• Number them by alphabetical priority, ignoring numerical
prefixes such as di- and tri-.
For halogen(iii)
• Treat them just like alkyl groups.
24. PHYSICAL PROPERTIES OF ALKANES
• Different physical properties
of alkanes is resulting from
different range of molecular
weight( different of c )
• On this subtopic we will cover
about
boiling point
Melting point
solubilty
25. Boiling Point
1) Increase smoothly with
increasing number of c
atoms(molecular
weight/molar mass)
•Greater number of C atom
•Large molecule
•Greater surface area
•Stronger Van Der Waals
attraction
•Higher boiling point
26. Example
CH3CH2 CH2 CH3 CH3 CH2 CH2 CH2 CH3 CH3 CH2 CH2 CH2 CH2 CH3
Butane Pentane Hexane
Bp=0° C Bp=36° C Bp=79° C
Increasing surface area
Increasing boiling point
27. Effect of Chain Branching
2) Branching of alkane
chain lowers boiling point
More branches
Molecular shapebecomes
more compact
Surface area reduced
Weaker Van Der Waals
attraction
Lower boiling point
29. Straight with Cycloalkane
• When compairing at the same number of
C, cycloalkanes has slightly higher boiling
point than alkanes.
Compairing Boiling Points to More
Polar Compounds
•Alkanes have low boiling points compared to
more polar compounds of comparable size
30. Example
CH3CH2 CH3 CH3CHO CH3CH2OH
Propane Acetaldehyde Ethanol
VDW VDW, DD VDW,DD,HB
MW=44 MW=44 MW=46
Bp= -42° C Bp=21° C Bp=79° C
Increasing surface area
Increasing boiling point
31. Melting Point
• Alkanes have low melting point compared
to more polar compounds
CH3CH2 CH3 CH3CHO
Propane Acetaldehyde
VDW VDW, DD
MW=44 MW=44
Mp= -190° C Mp=-121° CZ
Increasing strength of intermolecular forces
Increasing melting point
32. • Melting point increase as the number of
carbons increase because of increase of
surface area
CH3CH2 CH2 CH3 CH3 CH2 CH2 CH2 CH2 CH3
Butane Hexane
Mp=-138° C Mp=-95° C
Increasing surface area
Increasing boiling point
33. • Melting point increases with increased
symmetry
CH3CH2CH(CH3)2 (CH3)4C
Mp=-160° C Mp=-17° C
Increasing symmetry
Increasing melting point
34. Solubility in Water
• Alkanes are almost totally insoluble in
water
• They have low polarity and unable to form
hydrogen bonds
Solubility in Solvents
•Normally dissolve in solvent of low polarity
such as benzene. Chloroform, CCl4 and
other hydrocarbons.
41. 1.The root name is based on the longest
chain containing the halogen.
2.This root give the alkane part of the
name.
3.The type of halogen defines the halo
prefix, e.g. chloro-
4.The chain is numbered so as to give the
halogen the lowest possible number
42. 1.Functional group is an alkane, therefore
suffix = -ane
2.The longest continuous chain is C3
therefore root = prop
3.The substituent is a chlorine, therefore
prefix = chloro
4.The first point of difference rule
requires numbering from the right as
drawn, the substituent locant is 1-
1-chloropropane
CH3CH2CH2Cl
1-chloropropane
