Question

Aniline is more basic than cyclohexylamine because: (A) electrons on the aniline nitrogen are somewhat delocalized into the aromatic ring. (B) aniline is able to donate fewer hydrogens. (C) the protons on aniline are delocalized (D) protonation of aniline occurs on the benzene ring. (E) the above statement is false since aniline is less basic than cyclohexylamine.

Answer 1

Answer:

The correct answer is A electron on the aniline nitrogen are somehow delocalized to the aromatic ring.

Explanation:

The structure of aniline contain double bonds and lone pair of electron in the nitrogen atom of -NH2 group that is attached to the benzene ring.

  The electron pair present in the nitrogen atom of -NH3 group of aniline undergo delocalization with the aromatic ring of benzene resulting in the formation of resonance hybrid that increases the ability of nitrogen atom of -NH2 group of aniline to easily donate that lone pair of electron.

 ON the other hand the resonance stabilization cannot be possible with the cyclohexylamine ring as it is saturated.
