Question

Which one of the following statements is correct ?

(A) Stereoisomers which are nonsuperimposible mirror images are achiral

(B) Equimolar mixture of enantiomeric pair is called a racemic modification

(C) chemical properties of enantiomers are different

(D) A racemic modification is converted by an optically inactive agent into a mixture of

diastereomers that can be separated ​

Answer 1

(B) Equimolar mixture of enantiomeric pair is called a racemic modification

$\implies$ Correct Statement

• Equimolar concentration of left handed and right handed in an enantiomeric pair will lead to formation of a solution with optical inactivity.

• This is called racemic mixture.

• In this type of mixtures , the solution doesn't show any optical activity.

• This is because the left handed enantiomer rotates the light in the same magnitude and opposite direction as that of the right handed enantiomer.

• This results in zero deviation of light passing through the mixture.

Hope It Helps.

Answer 2

Answer:

• given statements are related to stereoisomers.            

• correct statement is

• B  =  equimolar mixture  of enantiomeric  pair is called  a racemic modification or racemic mixture

• other statements are false  stereoisomers which are nonsuperimposible mirror images are chiral not achiral

• chemical properties of enatiomers are same              

• racemic mixture have  equal functional group on both side .

• racemic mixture have zero optical rotation
