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:

1. Statement I is true but statement II is false.
2. Statement I is false but statement II is true.
3. Both statement I and statement II are true.
4. Both statement I and statement II are false.

Correct answer: Statement I is false but statement II is true.

Solution

Statement I is false because aniline is actually more basic than acetamide due to the presence of the electron-donating amino group, which increases the availability of the lone pair on nitrogen. Statement II is true as it correctly explains that the lone pair in aniline is delocalized into the benzene ring, making it less available to bond with protons.
