STANDARD Chemistry Nucleophilic Substitution Reactions MCQ Question
Type: MCQ-conceptual-Medium
Identify the products (A) and (B) in the reactions. RX + AgC≡N → (A) + AgX RX + KCN → (B) + KX
A
(A) – RCN, (B) – RCN
B
(A) – RCN, (B) – RNC
C
(A) – RNC, (B) – RCN
D
(A) – RNC, (B) – RNC
Correct Answer
Option C
Detailed Explanation
Both C and N can donate electron pairs. Since KCN is predominantly ionic and C–C bond is more stable than C–N bond in case of KCN, attack takes place through carbon atom. AgCN is predominantly covalent hence only nitrogen pair is available for bonding resulting in formation of isocyanide.
