Question

Acetophenone $(Ph-\overset{\underset{||}{O}}{C}- CH_3)$ is prepared in the laboratory by

• A.
• B.
• C.
• D. $Ph-\overset{\underset{||}{O}}{C}- Cl +CH_4 \xrightarrow {AlCl_3}$

Answer 1

Answer: (C)

Answer 2

Aromatic ketones can be prepared by Friedel-Craft's acylation or benzoylation. Acetophenone is prepared by the action of benzene with acetyl chloride in the presence of anhydrous $AlCl _{3}$. In this reaction the $H$-atom of benzene is replaced by acyl (- $COCH _{3}$ ) group.
This reaction is an example of electrophilic substitution reaction.
