- DD and E Only
Correct answer
A. A and B Only
Step-by-step solution
Reaction A: C₆H₅CH₂Br + AgCN C₆H₅CH₂NC + AgBr AgCN is predominantly covalent, so the nucleophilic attack occurs through the nitrogen atom, forming benzyl isocyanide. Reaction B: C₆H₅CH₂NH₂ + CHCl₃ + 3NaOH C₆H₅CH₂NC + 3NaCl + 3H₂O This is the carbylamine reaction. Primary amines react with chloroform and alkali to form isocyanides. Benzyl amine gives benzyl isocyanide. Reaction C: C₆H₅Br + AgCN No reaction Aryl halides are generally unreactive towards nucleophilic substitution under normal conditions due to the part
