Aniline on reaction with Bromine water gives:
Aniline on reaction with Bromine water gives:
Show Hint
Aromatic amines like aniline undergo electrophilic substitution easily due to the strong activating effect of the \(-\text{NH}_2\) group.

- 2,4,6-tribromoaniline
- m-bromoaniline
- p-bromoaniline

The Correct Option is B
Solution and Explanation
Aniline (\(\text{C}_6\text{H}_5\text{NH}_2\)) is highly reactive towards bromination due to the strong activating effect of the \(-\text{NH}_2\) group. When aniline is treated with bromine water, a white precipitate of 2,4,6-tribromoaniline forms:
\[
\text{C}_6\text{H}_5\text{NH}_2 + 3\text{Br}_2 \rightarrow \text{C}_6\text{H}_2\text{Br}_3\text{NH}_2 + 3\text{HBr}
\]
Since the \(-\text{NH}_2\) group is an electron-donating group, it directs substitution to the ortho and para positions, leading to tribromoaniline formation.
