Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Concept
Nucleophilic substitution of alkyl halides with silver salts like $AgCN$ favors the formation of isonitriles due to the covalent nature of the $Ag-CN$ bond.
Step 2: Meaning
Ethyl chloride reacts with $AgCN$ to produce ethyl isonitrile as the major product.
Step 3: Analysis
$KCN$ (ionic) would yield cyanide, whereas $AgCN$ (covalent) yields isocyanide/isonitrile.
Step 4: Conclusion
Set I is the only correct match for synthesizing ethyl isonitrile.
Final Answer: (C)
