18. Aromaticity / Acidity of Aromatic Hydrocarbons / Problem 9

Why is indene a stronger acid than indole even though the electronegativity of nitrogen is greater than that of carbon?

ANSWERS OPTIONS

A

Indene is a stronger acid than indole because of the strong inductive effect of nitrogen.

B

Indene is a stronger acid than indole because of a more electron-deficient carbon atom.

C

Indene is a stronger acid than indole because it gains aromaticity after deprotonation.

D

Indene is a stronger acid than indole because azepine loses aromaticity after deprotonation.
