What is true regarding a meso from of a compound?

A

A meso form is achiral due to the presence of an axis of symmetry

B

A meso form is achiral due to internal compensation of optical rotation

C

A meso form cannot be isolated from its optically active stereoisomer by fractional

D

A meso form does not contain any chiral carbon.

Text Solution

Verified by Experts

The correct Answer is:
B
A meso from, although containing chiral carbons, is optically inactive due to the presence of plane of symmetry. Optical activity of one half of the molecule is exactely cancelled by other half and is internally compensated.
