Sandmeyer reaction involves the replacement of diazonium group (- overset+N ≡ N) by -C l,-B r and -CN groups. ∴ Only PhCN , PhCl and PhBr can be formed by Sandmeyer reaction.

Q. How many of the following compounds CANNOT be formed by Sandmeyer reaction?
$P h CN, P h Cl, P h O H, P h I, P h F, P h B r, P h S O_{3} H, P h N O_{2}, P h S H .$

Sandmeyer reaction involves the replacement of diazonium group $(- N + \equiv N)$ by $- Cl, - B r$ and $- CN$ groups.
$∴$ Only $P h CN, P h Cl$ and $P h B r$ can be formed by Sandmeyer reaction.

Q. How many of the following compounds CANNOT be formed by Sandmeyer reaction? PhCN,PhCl,PhOH,PhI,PhF,PhBr,PhSO3​H,PhNO2​,PhSH.

Sandmeyer reaction involves the replacement of diazonium group (−N+≡N) by −Cl,−Br and −CN groups. ∴ Only PhCN,PhCl and PhBr can be formed by Sandmeyer reaction.
