Homework Answers
8) a) It contain two chiral centers.
b) Three stereoisomers are possible.
Number of stereoisomers = 2n = 22 = 4
Where n is number of chiral centers.
In this case two stereoisomers are same and are meso thus total three isomers are possible.
c) Enantiomers are non-superimposable mirror images and meso compound contain internal plane of symmetry which divide the molecule into teo equal halves.
Meso and Enantiomers are diastereomers with respect to each other.
Crossed structure is similar to meso structure thus only 3 ppssposs stereoisomers.
