Number of optically active isomers of tartaric acid is
–

The number of optically active isomers possible for - is -

It has chiral centre (*). It is-

Let g be the acceleration due to gravity at earth's surface and k be the rotational K.E of earth suppose the earth's radius decreases by 2% keeping alt other quantities same then

Optically active isomers but not mirror images are called -
