The correct Answer is:
To solve the assertion and reason question, we need to analyze both statements carefully. ### Step 1: Understanding the Assertion The assertion states that when an alkyl halide is reacted with AgCN, alkyl isocyanide is formed. - **Explanation**: Alkyl halides (R-X, where X is a halogen) can undergo nucleophilic substitution reactions. In this case, AgCN acts as a nucleophile. When AgCN reacts with an alkyl halide, the cyanide ion (CN⁻) attacks the carbon atom bonded to the halogen (X), leading to the formation of alkyl isocyanide (R-N≡C). ### Step 2: Understanding the Reason The reason states that AgCN is a covalent compound and only the site of nitrogen is available for the reaction. - **Explanation**: AgCN is indeed a covalent compound. In AgCN, the bond between silver (Ag) and the cyanide ion (CN) is covalent. The nitrogen atom in the cyanide ion has a lone pair of electrons, which makes it a good nucleophile. This lone pair is what allows the nitrogen to attack the carbon atom of the alkyl halide, facilitating the substitution reaction. ### Step 3: Conclusion Both the assertion and the reason are correct. The reason provided correctly explains why the assertion is true. ### Final Answer Both the assertion (A) and the reason (R) are correct, and R is the correct explanation of A.
