Ethylamine (C2H5NH2) can be obtained from N-ethylphthalimide on treatment with:

1. (1) CaH2
2. (2) H2O
3. (3) NaBH4
4. (4) NH2NH2

Correct answer: (4) NH2NH2

Solution

N-ethylphthalimide can be converted to ethylamine through a hydrazine (NH2NH2) reaction, which facilitates the cleavage of the phthalimide group, releasing ethylamine.
