Question

The end product C of the following reaction is

\[\ce{C2H5NH2 ->[HNO2] A ->[PCl5] B ->[NH3][Alcohol] C}\]

पर्याय

• Nitroethane

• Ethanol

• Chloroethane

• Ethanamine

Answer 1

Ethanamine

Explanation:

When ethylamine combines with nitrous acid, it produces ethanol as well as N₂ gas. Ethanol and phosphorus pentachloride react to generate ethyl chloride (C₂H₅CI), which then reacts with ammonia (NH₃) to form ethanamine. It's a reaction with two displacements.

\[\ce{\underset{\text{Ethanamine}}{C2H5NH2} ->[HNO2] \underset{\text{(A)}}{\underset{\text{Ethanol}}{C2H5OH}} ->[PCl5] \underset{\text{(B)}}{\underset{\text{Chloroethane}}{C2H5Cl}}->[NH3][Alcohol] \underset{\text{(C)}}{\underset{\text{Ethanamine}}{C2H5NH2}}}\]
