Question

in a particular reaction, styrene is produced by removing hydrogen from ethylbenzene. which type of reaction is this? a) hydration b) dehydrogenation c) reduction d) dehydration

Explanation:

• Option A: Hydration is the addition of water, not removal of hydrogen. Eliminate A.
• Option B: Dehydrogenation is the removal of hydrogen from a compound. Since the reaction removes hydrogen from ethylbenzene to form styrene, this matches.
• Option C: Reduction involves gaining electrons (often adding hydrogen or removing oxygen), opposite of removing hydrogen. Eliminate C.
• Option D: Dehydration is the removal of water, not hydrogen. Eliminate D.

Answer:

B) Dehydrogenation
