The reagent shown is warmed with an alcoholic solution of an amine and $KOH$ . Select all the amines (structures shown) that give a foul-smelling carbylamine product.

AStructure A
BStructure B
CStructure C
DStructure D

Answer: A, C

The reagent shown is chloroform. The carbylamine reaction is given only by primary amines, aliphatic or aromatic: isopropylamine (A) and p-toluidine (C). Trimethylamine (B) is tertiary and N-methylaniline (D) is secondary, so neither forms an isocyanide.
