Question

Explain it is easier to brominate aniline as compared to benzene

Answer 1

Explanation:

Any substituent on benzene which increases the π-electron density will increase the rate (ease) of bromination. -NH is an electron donating substituent (by loan pair of electrons on N atom). So the availability of π-electron in aniline is enhance the rate of substitution of aniline...

Answer 2

Availability of π-electron

Explanation:

• The formula of benzene and aniline are $C_6H_6$ and $C_6H_5NH_2$ respectively.
• Benzene, when substituted by any group which can increase the π-electron density on the benzene ring will increase the rate (ease) of bromination or it will be easier to brominate.
• In alinine the -NH group act as an electron-donating group ( presence of lone pair of electrons on N atom).

    ∴ The availability of π-electron in aniline makes it easier to brominate as compared to benzene.
