Solution
The correct option is D A, B, C are correct
Optical isomers are named such because of their effect on plane polarised light.
Simple substances which show optical isomerism exist as two isomers known as enantiomers.
A solution of one enantiomer rotates the plane of polarisation in a clockwise direction. This enantiomer is known as the (+) form.
A solution of the other enantiomer rotates the plane of polarisation in an anti-clockwise direction. This enantiomer is known as the (-) form.
They have chirality and almost the same physical & chemical properties.
But rotation of plane polarised light is opposite.
Option A correct.
