Given below are two statements: Statement I : Aniline is less basic than acetamide. Statement II : In aniline, the lone pair of electrons on nitrogen atom is delocalised over benzene ring due to resonance and hence less available to a proton. Choose the most appropriate option
Option: 1 Statement I is true but statement II is false.
Option: 2 Statement I is false but statement II is true.
Option: 3 Both statement I and statement II are true.
Option: 4 Both statement I and statement II are false.

Aniline is more basic than Acetamide

This is because of a greater extent of resonance of lone pairs of  N atom with the carbonyl group which causes a lessening of the electron cloud density on N.

Aniline also shows resonance with the lone pairs over N being delocalised on the Benzene ring. However, the extent of this resonance is less due to aromatic nature of Benzene ring.

Thus, statement I is false while statement II is true

Hence, the correct answer is option (2)
