The correct Answer is:
To solve the assertion-reason question, we will analyze both the assertion (A) and the reason (R) step by step. ### Step 1: Analyze the Assertion (A) The assertion states: "When alkyl halide is reacted with AgCN, then alkyl isocyanide is formed." - **Understanding the Reaction**: Alkyl halides (R-X, where X is a halogen) can react with silver cyanide (AgCN). The general reaction can be represented as: \[ R-X + AgCN \rightarrow R-NC + AgX \] - **Product Formation**: The product formed is indeed an alkyl isocyanide (R-NC). Thus, the assertion is **true**. ### Step 2: Analyze the Reason (R) The reason states: "AgCN is a covalent compound and only the site of nitrogen is available for the reaction." - **Nature of AgCN**: Silver cyanide (AgCN) is indeed a covalent compound. In this compound, the nitrogen atom is the nucleophilic site that attacks the electrophilic carbon in the alkyl halide. - **Availability of Reaction Site**: The statement that only the nitrogen site is available for the reaction is correct because the carbon in the cyanide group (C≡N) does not participate in the nucleophilic attack. Thus, the reason is also **true**. ### Step 3: Determine the Relationship Between A and R Now we need to check if the reason correctly explains the assertion. - The reason explains why the reaction occurs and why alkyl isocyanides are formed from the reaction of alkyl halides with AgCN. Since AgCN is covalent and the nitrogen is the reactive site, this supports the assertion. ### Conclusion Both the assertion (A) and the reason (R) are true, and the reason is the correct explanation of the assertion. ### Final Answer Both A and R are true, and R is the correct explanation of A. ---
