Factors affecting nucleophilic substitution reactions finished d
The document discusses four key factors that affect nucleophilic substitution reactions: 1) the nature of the substrate, 2) the nature of the nucleophile, 3) the nature of the solvent, and 4) the nature of the leaving group. It provides details on how each factor influences whether a reaction proceeds by an SN1 or SN2 mechanism. For the nature of the substrate, it explains that tertiary substrates favor SN1 and primary substrates favor SN2 due to steric effects. For the nucleophile, it states that small, less electronegative, stronger bases react faster in SN2. The document also discusses how solvent polarity and ionization potential influence SN1 vs SN2 mechanisms. Finally, it

Optical isomerism
This document discusses isomerism and stereochemistry. It defines isomers as compounds with the same molecular formula but different structures or arrangements. Isomerism includes structural isomers like chain, positional, and functional isomers as well as stereoisomers. Stereoisomers have the same connectivity but different spatial arrangements and include enantiomers, which are non-superimposable mirror images, and diastereomers. Chiral molecules lack symmetry elements like planes and centers of symmetry and cannot be superimposed on their mirror images, while achiral molecules can.

Steriochemistry ppt
This document provides an outline and overview of stereochemistry concepts including isomerism, chiral and achiral carbons, enantiomers, diastereomers, geometric isomerism, asymmetric synthesis, and optical resolution methods. Key topics covered are classification of isomers, properties of chiral carbons, differences between enantiomers and diastereomers, cis-trans isomers in cyclic compounds, how asymmetric synthesis produces unequal product amounts, and methods for separating enantiomers including mechanical, biochemical and chemical separation. Applications of stereochemistry in medicinal compounds and biological systems are also briefly discussed.
Sache mohr theory
Sachse-Mohr theory proposes that cyclic compounds like cyclohexane are not planar rings with strained carbon-carbon bonds, but rather exist in puckered, three-dimensional conformations that allow the carbon atoms to maintain their normal tetrahedral geometry and bond angles of 109.5 degrees without strain. Ernst Mohr later applied this theory to decalin, identifying its cis- and trans-isomers, supporting Sachse's hypothesis. The theory explains the observed stability of rings with six or more carbons and is now generally accepted.

Reactions of chiral molecules
The document discusses chiral molecules and their reactions. Chiral molecules have non-superimposable mirror images due to having four different groups attached to a carbon atom without symmetry. There are three major reactions for chiral molecules: retention, where the configuration of substrate and product remain the same; inversion, where the isomer converts to the other form through an SN2 mechanism; and racemization, where a second chiral center forms diastereomers.
Resolution of racemic mixture
The document discusses various methods for resolving a racemic mixture into its pure enantiomers, including:
1) Mechanical separation, which separates crystal forms of enantiomers
2) Preferential crystallization, which seeds a solution with a pure enantiomer to induce crystallization
3) Biochemical separation using microorganisms that metabolize one enantiomer more quickly
4) Chromatographic separation exploiting differences in how enantiomers adsorb to a chiral support
5) Kinetic methods using reactions that proceed at different rates for each enantiomer

Baeyer's Strain theory.pptx
Cycloalkane stability is explained by Baeyer's Strain Theory, which states that deviations from the ideal tetrahedral bond angle of 109.5° impose strain. Cyclopropane has the most angle strain due to 60° bonds, making it highly unstable and prone to ring-opening. Cyclobutane has less strain from 90° bonds. Larger rings like cyclopentane and cyclohexane have less strain as their bond angles are closer to 109.5°. Baeyer assumed rings were flat, but they are actually puckered, allowing bonds to approach 109.5°. Rings larger than cyclopentane have little strain and are as stable as open-chain alkanes.

Coulsonand moffittsmodification
Coulson and Moffitt proposed that the carbon-carbon bonds in cyclopropane rings are bent based on quantum mechanical calculations. This idea of bent bonds is supported by electron density maps from X-ray studies. Molecular orbital theory explains that the overlap of orbital axes is maximized in cyclohexane, resulting in stronger carbon-carbon bonds, whereas in cyclopropane the orbital overlap is less, making the bonds weaker and allowing for ring-opening. Factors like bond angle strain from deviations from normal tetrahedral angles, torsional strain from non-staggered conformations, and steric strain from van der Waals repulsion between non-bonded atoms all contribute to the relative stability of different molecular conformations

Phenols: methods of preparation, chemical reaction
The document discusses the properties and reactions of phenols. Phenols contain a hydroxyl group directly attached to a benzene ring. They are more acidic than alcohols due to resonance stabilization of the phenoxide ion. Phenols undergo electrophilic aromatic substitution at the ortho- and para-positions. They are also oxidized by strong oxidizing agents. Common phenols include phenol, cresols, and resorcinol. Phenol is used as an antiseptic and in making resins, plastics and drugs. Cresols are used as herbicides, antioxidants and preservatives. Resorcinol is used as an antiseptic and disinfectant.
Relative Aromaticity & Reactivity of Pyrrole, Furan & Thiophene
Pyrrole, furan, and thiophene can all be aromatic according to Hückel's rule. Thiophene exhibits the greatest aromaticity followed by pyrrole then furan. This order correlates with the electronegativity of the heteroatoms, with sulfur being the least electronegative. In terms of reactivity towards electrophilic substitution, pyrrole reacts most readily followed by furan then thiophene. Pyrrole's carbon atoms are most electron-rich due to nitrogen's mesomeric effect outweighing its inductive effect.
Size separation
Size separation, also known as screening or sieving, involves separating particles into two or more portions based on differences in particle size, shape, and density. This is done using screening surfaces with meshes of different sizes. Common methods of size separation include sieving using oscillation, vibration, gyration, brushing, or centrifugal force to separate particles. Size separation is useful for obtaining specific particle size ranges for applications like tablet and capsule production.

Elimination reaction
- Elimination reactions occur by either an E1 or E2 mechanism. E1 is a one-step reaction involving a carbocation intermediate, while E2 is a concerted, single-step reaction.
- The E1 mechanism is favored by good leaving groups, stable carbocations, and weak bases. It is non-stereospecific and does not occur with primary alkyl halides. The E2 mechanism is favored by strong bases and polar aprotic solvents. It is stereospecific and proceeds through an anti-periplanar transition state.
- Key factors that determine the mechanism include the stability of carbocation intermediates, the strength of the leaving group and base, and steric
Micelle and Critical Micelle Concentration
Critical micelle concentration refers to the minimum concentration of surfactant above which micelles start to form spontaneously in a solution. It is an important characteristic of surfactants that can be determined through measuring changes in properties like surface tension, conductivity, and turbidity at varying concentrations. Several factors influence the critical micelle concentration, including the structure of the surfactant's hydrophobic group and the presence of electrolytes in the solution.
SIEVING METHOD.pptx
This document summarizes the sieving method for separating fine and coarse powders. The sieving method involves passing powdered material through a set of sieves arranged from largest to smallest size to separate particles by size, with the smallest particles passing through to the bottom collection pan. Powder size is determined by the smallest sieve it can pass through. Sieves are shaken to allow particles to pass through while preventing clogging, though attrition may occur during shaking. The sieving method is inexpensive and easy to use but powders must be dry to prevent clogging and potential attrition from shaking.

Pastes
Pastes are semisolid dosage forms containing a high percentage (50% or more) of insoluble solids dispersed in a suitable base. They adhere well to the skin and are used to treat chronic lesions. Pastes are stiffer than creams and ointments, so they remain stable at the site of application and allow perspiration to escape while not interfering with uninfected skin. Pastes are classified based on their base as fatty, aqueous gel, or hydrocolloid pastes. They are prepared by trituration or fusion and contain ingredients like zinc oxide, coal tar, or aluminum oxide dispersed in a hydrophobic or water-miscible base. Evaluation parameters include mechanical strength tests and liquid phase migration studies.
Suppository
This document provides information on suppositories including their history, definition, types, anatomy and physiology of the rectum, absorption from the rectum, factors influencing drug absorption, formulation, and manufacturing. Key points:
- Suppositories were first used in the 18th century by a French pharmacist for rectal drug administration.
- They are solid or semi-solid dosage forms meant to melt or soften at body temperature for local or systemic drug delivery via body cavities like the rectum.
- The rectum is well-suited for drug absorption due to its blood supply and pH. Suppositories can deliver drugs systemically by bypassing first-pass metabolism.

simplified modulation technique paves the way for more straightforward and
efficient control of multilevel inverters, enabling their widespread adoption and
integration into modern power electronic systems. Through the amalgamation of
sinusoidal pulse width modulation (SPWM) with a high-frequency square wave
pulse, this controlling technique attains energy equilibrium across the coupling
capacitor. The modulation scheme incorporates a simplified switching pattern
and a decreased count of voltage references, thereby simplifying the control
algorithm.
