• # question_answer Which of the following is Friedel-Craft?s reaction [MP PET 1994] A) ${{C}_{6}}{{H}_{6}}+FeC{{l}_{3}}+C{{l}_{2}}\to {{C}_{6}}{{H}_{5}}Cl$ B) ${{C}_{6}}{{H}_{5}}CHO+C{{H}_{3}}CHO+KOH\to {{C}_{6}}{{H}_{5}}CH=CH-CHO$ C) ${{C}_{6}}{{H}_{6}}+C{{H}_{3}}COCl+AlC{{l}_{3}}\to \overset{\,\,\,O}{\mathop{\overset{\,\,\,\,||}{\mathop{{{C}_{6}}{{H}_{5}}-C-C{{H}_{3}}}}\,}}\,$ D) ${{C}_{6}}{{H}_{5}}OH+CHC{{l}_{3}}+KOH\xrightarrow{{}}\text{Salicylaldehyde}$

Friedel-craft?s reaction $\underset{\text{Acetyl chloride}}{\mathop{C{{H}_{3}}COCl}}\,+\underset{\text{Benzene}}{\mathop{{{C}_{6}}{{H}_{6}}}}\,\xrightarrow{\text{anhydrous }AlC{{l}_{3}}}\underset{\text{Acetophenone}}{\mathop{C{{H}_{3}}CO{{C}_{6}}{{H}_{5}}}}\,+HCl$
