GPAT Syllabus/ Organic chemistry / Stereochemistry
11. Stereochemistry
Stereochemistry. Chirality
& asymmetry [introduction of the same to S, P, & N]. Definition
& classification [different types of isomerisms]. Enantiomers,
diastereomers. Enantiomerism & diastereomerism. Meso compounds & their
optical activity. Stereochemistry
in acyclic compounds. Newman
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.
Chair conformations of cis-, & trans-decalins, perhydrophenanthrenes, &
a tetracyclic steroidal nucleus. An introduction to atropisomerism.
