Answer to Question #128554 in Organic Chemistry for Kamli Ramli

Question

Why benzofuran is more stable than furan towards acid?

Answer 1

Solution.

Like furan, benzofuran is an aromatic compound. But benzofuran is more resistant to acid than furan, since there is an additional benzene ring in the benzofuran, the presence of which leads to stabilization of the resonant structure, due to the redistribution of the electron density in the benzofuran.
