Unit 1
Introduction to organic chemistry: Lewis structure and formal charges of organic compounds – electro negativities and dipoles, resonances, aromaticity and anti aromaticity – equilibrium, tautomerism and hyper conjugation – acidity and basicity – pKa, nucleophiles and electrophiles – hydrogen bonding – different types of organic reaction – addition, substitution, elimination and rearrangement – oxidations and reductions – general principles of writing organic reaction mechanism – reactive intermediates.
Reaction of nucleophiles and bases: Nucleophilic substitution – SN1 and SN2 reactions, nucleophilic substitution at aliphatic sp2 carbon and aromatic carbon – nucleophilic addition to carbonyl compounds – addition of grignard and organo lithium reagents – reactions of nitrogen containing nucleophiles with aldehyde and ketones – aldol condensation.
