Question

In the following scheme of reaction.

X, Y and Z respectively are:

• A. AgF, alcoholic KOH, benzene
• B. HF, aqueous KOH, Na in dry ether
• C. $Hg_2F_2$​, alcoholic KOH, Na in dry ether
• D. $CoF_2$​, aqueous KOH, benzene

Hint:

C2​H5​Cl converts to C2​H5​F via HgF2​, then dehydrohalogenates to ethene, forming butane via Wurtz coupling.

Answer 1

The Correct Option is C

$C_2​H_5​Cl$ is converted to $C_2​H_5​F$ using $HgF_2​$. Dehydrohalogenation with alcoholic KOH produces ethene, which undergoes Wurtz coupling with sodium in dry ether to form butane.
