Question

The end product of the reactions is
C₂H₅NH₂□(→┴(HNO₂) )A□(→┴(PCl₅) )B□(→┴(H.NH₂) )
(a) ethyl cyanide (b) ethyl amine
(c) methyl amine (d) acetamide

Answer 1

$\huge{\underline{\mathbb{\red{Answer}}}}$

(c) methyl amine

Answer 2

The end product of the reactions is

(b) ethyl amine

When alkyl amines react with HNO₂, alcohols are produced.

So, ethyl amine on reaction with HNO₂ will produce ethanol (C₂H₅OH)

Ethanol on reaction with Phosphorus pentachloride, will produce ethyl chloride (C₂H₅Cl)

Ethyl chloride on reaction with ammonia will produce ethyl amine (C₂H₅NH₂)

The reactions are:

C₂H₅NH₂□(→┴(HNO₂) )A = C₂H₅OH□(→┴(PCl₅) )B = C₂H₅Cl □(→┴(H.NH₂) ) C₂H₅NH₂

Option (b) is correct.
