& classification [different types of isomerisms]. Enantiomers,
diastereomers. Enantiomerism & diastereomerism. Meso compounds & their
optical activity. Stereochemistry

projection formulae & their significance. Conformational
analysis of nbutane. Absolute & relative
configuration. Assigning
R & S configuration based on Cahn Ingold & Prelog system. Racemic
mixture- its definition & resolution. Definitions of terms stereoselective,
stereospecific, Enantiomeric excess & diastereomeric excess. Stereochemistry
in cyclic systems. Conformations
of cyclohexane. Cis-trans relationship in cyclohexane. Prediction of stability
of different conformations of 1, 2- 1,3- & 1,4- disubstituted cyclohexanes.
Effect of multiple substitutions on the stability of cyclohexane conformations.
