An unknown substance (P) shows optical activity. This optical activity disappears on treatment of (P) with acidified `KMnO_(4)` (which produces Q), or with heated copper (which produces R). (P) Produces silver mirror with Tollen's reagent, thereby producing (S). (S) is chiral. Based on this information, answer the following questions :
(P) may be-

A

2

B

3

C

4

D

Text Solution

Verified by Experts

The correct Answer is:
A

One chiral center may have (R) or (S) configuratoin. Hence, two stereoisomers.
