Which of the following reagents would distinguish ciscyclopenta `-1,2-`diol from the trans-isomer?

A

`MnO_(2)`

B

Aluminium isopropoxide

C

Acetone

D

Ozone

Text Solution

Verified by Experts

The correct Answer is:
C
A cyclic ketal contains a five-membered ring. Since two fused five membered rings are more stable if the fusion is cis, therefore, cis-cyclopentane-1,2-diol forms a stable ketal with acetone but trans isomer does not react.
