Question

The number of configurational isomers of molecules having (n) different chiral carbons is ____________

(a) 2n

(b) 2^n

(c) 2^n-1

(d) 2^n+1

I have been asked this question during an online interview.

I'd like to ask this question from Optical Isomerism in section Structure and Stereostructure of Molecules of Engineering Chemistry I

Answer 1

The correct option is (b) 2^n

To explain I would say: The number of configurational isomers of molecules having (n) different chiral carbons is 2^n. It is calculated mathematically.
