Question

N −Ethyl pthalimide on hydrolysis gives:
A.methyl alcohol
B.ethyl amine
C.dimethyl amine
D.diethyl amine

Answer 1

Hint : The N-hydroxy derivative of phthalimide is N-hydroxyphthalimide. The compound is used as a catalyst for oxidation reactions, specifically the selective oxidation of alkanes to alcohols with molecular oxygen under mild conditions.

Complete Step By Step Answer:
A.methyl alcohol is wrong answer. Because on hydrolysis N −Ethyl pthalimide does not give methyl alcohol. Modern methanol production relies on the direct reaction of carbon monoxide gas and hydrogen in the presence of a catalyst.
B. ethyl amine is the correct answer. Because Ethyl amine is generated by the alkaline hydrolysis of N-ethylpthalimide. The organic compound ethylamine has the formula $C{H_3}C{H_2}N{H_2}$. The odour of this colourless gas is similar to that of ammonia. It condenses to a liquid miscible with nearly all solvents at just below room temperature. As is typical of amines, it is a nucleophilic base. In the chemical industry and organic synthesis, ethylamine is commonly used.
C. dimethyl amine is wrong answer. Because on hydrolysis N −Ethyl pthalimide does not give dimethyl amine. This secondary amine is a flammable, colourless gas that smells like ammonia. Dimethylamine is typically used in industrial applications as a solution in water with concentrations up to$40\%$.
D. diethyl amine is wrong answer. Because on hydrolysis N −Ethyl pthalimide does not give diethyl amine. Diethylamine is a transparent, colourless liquid that smells like ammonia. Eyes and skin are corroded. Vapors are denser than air. During combustion, toxic nitrogen oxides are formed.
So in conclusion, we can say that N −Ethyl pthalimide on hydrolysis gives ethyl amine.

Note :
Any chemical reaction in which a water molecule breaks one or more chemical bonds is known as hydrolysis. The term refers to any substitution, reduction, or solvation reaction in which the nucleophile is water.
