This document contains notes from a presentation on organic chemistry. It includes an outline of topics typically covered in high school, undergraduate, and postgraduate organic chemistry courses. It also provides examples of questions asked to chemistry students after completing high school, responses to those questions, and links to online chemistry resources. The presenter suggests some alternative teaching methods like asking students to submit their own questions rather than routine homework, and providing questions for students to evaluate answers to promote critical thinking.

Synthetic Fiber Construction in lab .pptxPavel ( NSTU)
Synthetic fiber production is a fascinating and complex field that blends chemistry, engineering, and environmental science. By understanding these aspects, students can gain a comprehensive view of synthetic fiber production, its impact on society and the environment, and the potential for future innovations. Synthetic fibers play a crucial role in modern society, impacting various aspects of daily life, industry, and the environment. ynthetic fibers are integral to modern life, offering a range of benefits from cost-effectiveness and versatility to innovative applications and performance characteristics. While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

* brief discussion on an ongoing survey
• Some examples from high school textbooks
• Asking questions
• Organic chemistry curricula in UG and PG levels
• Computers/internet – useful resources, a few examples
• Some interesting thoughts
5. Organic Chemistry in High School
End of Class 11

6. •Your name
• Your high school name and location:
• When did you first study Chemistry as a separate subject?
• Which topics/chapters in Chemistry did you like the most? Why?
• Which topics/chapters in Chemistry did not interest you at all? Why?
• Did you do any laboratory experiments?
• Which experiments did you do? Which one did you like the most?
• Did you do any chemistry experiment (e.g. a project) not connected with your
syllabus? If so, please give some details.
• Did any of your chemistry teachers use an innovative method to teach? If so,
could you briefly describe?
• Do you think Chemistry teaching in schools needs to be improved? If the answer
is yes, could you say in a few lines what differences would have made you more
interested in Chemistry?
Questions asked to students who finished high school in 2014
7. Which topics/chapters in Chemistry did you like the most?
• Organic Chemistry, since no memorization was required once you know the
concepts
• Organic chemistry as it is fun to know how reaction works and making new
compounds using reactions
• States of matter, Chemical bonding and Molecular Structure
• ‘Atomic structure', 'bonding' were and are the subjects which fascinate me
• The atomic structure, Chemical bonding, Electro-chemistry, Coordination
chemistry and Organic mechanisms
• Organic Chemistry part, because I find some logical things here, where I can
use my brain, to propose a mechanism, or to explain why something is happening
like that, & this organic part is much more organized.
• Periodic table properties. It was well organized.
• I like the chemistry in everyday life and the chemistry behind the things
which happen in our surrounding
Representative response to four important questions
8. Which topics/chapters in Chemistry did not interest you at all?
• Thermodynamics, Organic, s, p and d-block elements because I did not
understand the mechanism of organic molecules
• Solid state chemistry
• Thermodynamics, surface chemistry
• 'Electrolytic solutions' and all those normality molarity calculations were boring;
so were the Board’s syllabi on inorganic chemistry.
• Electrochemistry. The flow of electrons was not clearly explained
• Kinetic theory of gas, I don't know why
• The detailed study of the Periodic table
• Chemistry of p-block elements
9. Did any of your chemistry teachers use an innovative method to
teach?
• Used models to teach organic chemistry and structures
• Yes, he used ball and stick models while teaching stereochemistry
• Yes, one of them, but most of them were monotonous.
• NO. They have taught some remembering techniques like...VIBGYOR
• Yes. one of our teacher showed us many experiments when we were in
class VIII.
10. Do you think Chemistry teaching in schools needs to be improved?
• More practicals and more reaction mechanisms, may be.
• Yes. Labs are not well equipped. Not funded properly. Scarcity of compounds and
reactants like Nessler reagent
• Inorganic chemistry should be taught conceptually and the syllabus should be
accordingly changed.
• Reaction Mechanisms have to be introduced before one starts reading about
organic chemistry
• Yes, Teachers can use projectors and pictures. No one thinks that remembering
hard reactions are the main part of Chemistry.
• Use some e-technology to show the actual things which we r studying as theory.
using some model, doing experiments from very basic levels
• All the teachers teach organic reactions without reaction mechanism
• More practicals
• Various software, models and Internet should be taken to teach chemical and
crystal structures
• Chemistry needs to be taught in a more interactive manner, and should not solely
test the memory skills of a student. Demonstrations and visually stimulating
experiments related to the concepts being taught can motivate many students to
look at chemistry as a viable career option.
15. “My mother made me a scientist without ever intending to. Every
other Jewish mother in Brooklyn would ask her child after school:
So? Did you learn anything today? But not my mother. “Izzy,”
she would say, “did you ask a good question today?” That
difference — asking good questions — made me become a
scientist.”
The Nobel Prize in Physics 1944 was awarded
to Isidor Isaac Rabi "for his resonance
method for recording the magnetic properties
of atomic nuclei".

compound 2?Give abrief explanation. [2 +
2 = 4]
Theobserved KIE withcompound2 willbe less
than 1.11.
This is becausetheC-Hbond is longerthan theC-Dbondand thus less strain is
