The chemicals used for preparing acetophenone are
(A) $\mathrm{C}_6 \mathrm{H}_6$
(B) $\mathrm{CH}_3 \mathrm{COCH}_3$
(C) $\mathrm{CH}_3 \mathrm{COCl}$
(D) Anhydrous $\mathrm{AlCl}_3$
$A, B, C$

$A, B, D$
$A, C, D$
Solution
Acetophenone can be prepared as
$\mathrm{C}_6 \mathrm{H}_6+\mathrm{CH}_3 \mathrm{COCl} \underset{\text { Friedel-Crafts reaction }}{\stackrel{\text { anhyd }\cdot \mathrm{AlCl}_3}{\longrightarrow}}$\mathrm{C}_6 \mathrm{H}_5 \mathrm{COCH}_3+\mathrm{HCl}$
