Solution
The correct option is B Racemic mixture
Equimolar mixture of d and l forms of an optically active compound is known as racemic mixture.
A racemic mixture is optically inactive due to the external compensation of equal precentage of (+) and (-) forms.
Example:
Equal amounts of d and l forms of lactic acid in a mixture.
50% (l)-lactic acid and 50% (d)-lactic acid is a racemic mixture. Both counterbalances each other to form a racemic mixture.
