Question

Aniline reacts with bromine water at room temperature to give

• A. 3-bromoaniline
• B. 2-bromoaniline
• C. 4-bromoaniline
• D. 2,4,6-tribromoaniline

Hint:

Strongly activating groups cause multiple substitutions in electrophilic aromatic substitution reactions.

Answer 1

The Correct Option is D

Step 1: Nature of aniline.
Aniline contains an amino group which is a strong activating and ortho-para directing group.

Step 2: Reaction with bromine water.
Due to strong activation, bromination occurs rapidly at ortho and para positions without catalyst.

Step 3: Product formation.
Substitution occurs at 2, 4, and 6 positions, forming 2,4,6-tribromoaniline.

Step 4: Conclusion.
Hence, the product formed is 2,4,6-tribromoaniline.
