MHT CET Chemistry Question (2026) — Solution

Step-by-step solution

Alkyl halides react with alcoholic silver cyanide ( AgCN ) to form alkyl isocyanides as the major product. AgCN is predominantly covalent in nature, so only the nitrogen atom has a lone pair of electrons available for nucleophilic attack. This leads to the formation of an alkyl isocyanide ( RNC ). R-X + AgCN R-NC + AgX In contrast, KCN gives alkyl cyanides, KNO _2 gives alkyl nitrites, and AgNO _2 gives nitroalkanes. Answer: AgCN (alco)
