Question

Assertion: Ethyl chloride with ethanolic $AgCN$ gives ethyl isocyanide as major product.
Reason: In ethyl cyanide, carbon of $CN$ group is $sp$ hybridised.

• A. Both Assertion and Reason are true and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are true and Reason is not the correct explanation for Assertion
• C. Assertion is true and Reason is false
• D. Assertion is false but Reason is true

Answer 1

The correct option is B Both Assertion and Reason are true and Reason is not the correct explanation for Assertion

$C_2{H}_5-Cl+AgCN⟶C_2{H}_5-NC+AgCl$

A structure of ethyl cyanide $C{H}_3-C{H}_2-C\equiv N$, so in $-CN$ carbon is sp hybridized.

Ethyl chloride reacts with $KCN/NaCN$ and alkyl cyanide forms, but ethyl chloride reacts with $AgCN$ and isocyanide forms.

Option B is correct.
