Question

Which of the following organic chloride will not give a Friedel-Craft alkylation product when heated with benzene and $AlC{l}_3$?

• A. $(C{H}_3{)}_{3}CCl$
• B. $C{H}_2=CHC{H}_{2}Cl$
• C. $C{H}_{3}C{H}_{2}Cl$
• D. $C{H}_2=CHCl$

Answer 1

The correct option is A $(C{H}_3{)}_{3}CCl$

$(C{H}_3{)}_{3}CCl$ will not give friedel craft alkylation product when located with benzene and $AlC{l}_3$.
Friedel craft alkylation involves the alkylation of an aromatic ring with an alkyl halide using a strong lewis acid catalyst weak anhydrous ferric chloride as a catalyst , the alkyl group attaches at the former site of the chloride ion.
