Q. How many of the following compounds CANNOT be formed by Sandmeyer reaction?
$PhCN , PhCl , PhOH , PhI , PhF , PhBr , PhSO _{3} H, PhNO _{2}, PhSH .$

Amines

Solution:

Sandmeyer reaction involves the replacement of diazonium group $(-\overset{+}{N} \equiv N)$ by $-C l,-B r$ and $-CN$ groups.
$\therefore $ Only $PhCN , PhCl$ and $PhBr$ can be formed by Sandmeyer reaction.
