Question

Can number of stereoisomers possible for a compound be odd

Answer 1

Explanation:

Again, we see that if the molecule has the same geometrical configuration at the first and the third double bond, then the molecule has a plane of symmetry. ... If 'n' is even (here n is the number of double bonds):Number of stereoisomers=2n−1+2n/2−1. If 'n' is odd, then: Number of stereoisomers=2n−1+2(n−1)/2.
