Question

Two statements are given below 
Statement I: Benzanamine can be prepared from phthalimide. 
Statement II: Benzanamine is less basic than phenyl methanamine.

• A. Both statements I \& II are correct
• B. Both statements I \& II are not correct
• C. Statement I is correct, but statement II is not correct
• D. Statement I is not correct, but statement II is correct

Hint:

The basicity of amines is influenced by the availability of the nitrogen's lone pair of electrons for protonation. Aromatic amines are generally less basic than aliphatic amines due to electron delocalization.

Answer 1

The Correct Option is D

Statement I: Benzanamine (aniline) cannot be prepared directly from phthalimide. Phthalimide is typically used in the Gabriel synthesis to prepare primary aliphatic amines, not aromatic amines like benzanamine. Therefore, Statement I is not correct.

Statement II: Benzanamine (aniline) is less basic than phenyl methanamine (benzylamine). This is because the lone pair of electrons on the nitrogen in aniline is delocalized into the benzene ring, reducing its availability for protonation, whereas in benzylamine, the nitrogen's lone pair is more available for protonation. Thus, Statement II is correct.

Final Answer:
Statement I is not correct, but statement II is correct.
