Question

What hybridization change occurs when an alkyne is partially hydrogenated to an alkene?
Options
A sp → sp²
Correct Answer
B sp² → sp³
C sp → sp³
D sp² → sp
Correct Answer

Option A is the correct answer.

Detailed Explanation

Partial hydrogenation (e.g., Lindlar) converts sp‑hybridized alkyne carbons to sp²‑hybridized alkene carbons.

Hint

Triple bond becomes double bond.
