Question

The sufficient condition for showing optical activity is _______________

(a) Molecule should have measurable amount of optical activity only

(b) Polarimeter should have capacity of recording low-degree optical activity only

(c) Chirality of molecule as a whole only

(d) Both, the molecule should have measurable amount of optical activity and polarimeter should have capacity of recording low-degree optical activity

This question was posed to me in exam.

This key question is from Optical Isomerism in section Structure and Stereostructure of Molecules of Engineering Chemistry I

Answer 1

The correct choice is (d) Both, the molecule should have measurable amount of optical activity and polarimeter should have capacity of recording low-degree optical activity

The best explanation: The molecule should have measurable amount of optical activity and polarimeter should have capacity of recording low-degree optical activity.
