Acids and Bases
Concepts of acids and bases; scale of acidity and basicity; pKa values; predicting acid/base reactions from pKa values; the effect of structure on the strengths of acids and bases, field effects, resonance effects, steric effects, hydrogen bonding effects and hybridization effects; the effect of the medium on the strengths of acids and bases; the Hammett and Taft’s equation applications and limitations.
Aliphatic Nucleophilic Substitution
Mechanism of SN1, SN2 and SNi. Neighbouring group participation: Intramolecular displacement by O, N, S and X. The effect of substrate structure, entering, leaving group and reaction medium on the mechanism and rates of substitution reactions.
Mechanism of E1, E2, and E1cB
Orientation: Saytzeff and Hofmann rules
The effect of substrate structure, attacking base, leaving group and reaction medium on the rates and mechanisms of elimination reactions.
Aromatic Substitution Reactions
Electrophilic substitution: Aromaticity, mechanism, orientation and reactivity
Electrophilic substitution reactions: Nitration, halogenation, sulfonation, Friedel-Crafts reaction, diazo-coupling, formylation and carboxylation.
Aromatic Nucleophilic Substitution
Mechanism of SN Ar.
The effect of substrate structure, leaving group and attacking nucleophile on the rates of substitution reactions.
Purification Techniques: Sublimation technique
Mixture Analysis: Analysis of two component mixtures.
the course contains concept of Acids and bases, importance and role of Pka values in an reaction. nucleophilic substitution is also part of this syllabus, mechanism of substitution reaction and stereochemistry is also discussed. Substitution reaction in aromatic reaction also play a very important role in synthetic chemistry. Elimination reactions , factor effection on elimination reactions and mechanism of Elimination reactions is also including in this course.
