Q.
Identify $X, Y$ and $Z$ in the given sequence of reactions.
Amines
Solution:
Reaction of aniline with bromine water at room temperature produces a white precipitate of $2,4,6$ - tribromoaniline, this on reaction with nitrous acid produces diazonium salt. In aniline, the maximum electron density is found at ortho- and parapositions of the $- NH _{2}$ group. The $- NH _{2}$ group is ortho and para directing and is a powerful activating group.
