Tartaric acid [HO(2)CCH(OH)CH(OH)CO(2)H]...

Tartaric acid `[HO_(2)CCH(OH)CH(OH)CO_(2)H]` was an important compound in history of stereochemistry.
Two naturally occuring forms of tartaric acid are optically inactive. One optically inactive form (P) has a melting point of 210-`212^(@)`C and can be separated into two optically acitve forms, whereas other optically inactive form (Q) cannot be resolved further.
Optically inactive form Q is

A

Optically inactive due to internal compensation.

B

Optically inactive due to presence of plane of symmetry.

C

Optically inactive due to external compensation.

D

Optically inactive due to intramoleuclar hydrogen bonding.

Compound which rotates the plane polarised light is known as optically active compound . On the basis of direction of rotation two forms of an optically active compounds are termed as dextro and laevo rotatory . The two are termed as enantiomers . If we have a 1 : 1 mixture of d and l isomers of a given chiral compound , optical rotation of such mixture is zero Such a mixture is optically inactive and is called a recemic modification.
