Question

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 above statements, choose the correct answer from the options given below:

Canvas Classes · Accepted Answer

Assertion A: Glycine () + /red P (Hell-Volhard-Zelinsky reaction):

Product = -chloroglycine ()

The -carbon now has 4 different groups: , H, Cl,  → chiral carbon ✓

Assertion A is true.

Reason R: A molecule with 2 chiral carbons is NOT always optically active — it can be a meso compound (internal plane of symmetry makes it optically inactive). Reason R is false. ✗

Answer: Option (1) — A is true but R is false
