Question

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A) : Haloalkanes react with KCN to form alkyl cyanides as a main product while with AgCN form isocyanide as the main product.
Reason (R) : KCN and AgCN both are highly ionic compounds. In the light of the above statement
Choose the most appropriate answer from the options given below:

• A. (A) is correct but (R) is not correct
• B. Both (A) and (R) are correct but (R) is not the correct explanation of (A)
• C. (A) is not correct but (R) is correct
• D. Both (A) and (R) are correct and (R) is the correct explanation of (A)

Answer 1

The Correct Option is A

AgCN is mainly covalent in nature, and nitrogen is available for attack, so alkyl isocyanide is formed as the main product.
Thus, the correct answer is Option A.
