Solution


Q.

Given below are two statements, one is labelled as Assertion A and the other is labelled as Reason R.

Assertion A: A solution of the product obtained by heating a mole of glycine with a mole of chlorine in presence of red phosphorous generates chiral carbon atom.

Reason R: A molecule with 2 chiral carbons is always optically active.

In the light of the above statements, choose the correct answer from the options given below:               [2023]
1 Both A and R are true but R is NOT the correct explanation of A.  
2 A is true but R is false  
3 A is false but R is true  
4 Both A and R are true and R is the correct explanation of A.  

Ans.

(2)

Optical activity does not depend on chiral carbon. Meso compounds are optically inactive.
