Which of the following amines will produce an intensely foul-smelling substance when heated with chloroform and ethanolic potassium hydroxide, but fails to form a stable diazonium salt at 273 - 278 K ?

Step-by-step solution

The formation of an intensely foul-smelling substance when heated with chloroform and ethanolic potassium hydroxide is the carbylamine reaction, which is a characteristic test for primary amines (both aliphatic and aromatic). The failure to form a stable diazonium salt at 273 - 278 K indicates that the amine is an aliphatic primary amine. Aromatic primary amines form stable diazonium salts at this temperature due to resonance stabilization, whereas aliphatic primary amines form highly unstable diazonium salts that
