Question

For a molecule with two like chiral carbon atoms, the number of optically inactive form is?

(a) 1

(b) 2

(c) 3

(d) 4

This question was posed to me in homework.

The above asked question is from Optical Isomerism topic in section Structure and Stereostructure of Molecules of Engineering Chemistry I

Answer 1

Right choice is (a) 1

Best explanation: For a molecule with two like chiral carbon atoms, the number of optically inactive form is one. This is always used for the calculation of optically inactive forms.
