Compounds `(B)` and `(C)` are `:`

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
d
Both the cyclopropane rings are unstable because they are highly strained. They undergo hydrogenation with `H_(2)+Pt` and give `n-`octane and `(`or`)2,5-`dimethyl hexane. Hydrogenation with `P-2` catalyst converts `(C-=C)` to `(C=C)` only. So the answer is `(d)`.
