Question

The reaction of compound P with $C{H}_{3}MgBr$(excess) in $(C_2{H}_5{)}_{2}O$ followed by addition of $H_{2}O$ gives Q. The compound Q on treatment with $H_{2}S{O}_4$ at $0^{\circ }C$ gives R. The reaction of R with $C{H}_{3}COCl$ in the presence of anhydrous $AlC{l}_3$ in $C{H}_{2}C{l}_2$ followed by treatment with $H_{2}O$ produces compound S [Et in compound P is ethyl group]


The reactions, Q to R and R to S, are:

• A. Dehydration and Friedel-Crafts acylation
• B. Aromatic sulfonation and Friedel-Crafts acylation
• C. Friedel-Crafts alkylation, dehydration and Friedel-Crafts acylation
• D. Friedel-Crafts alkylation and Friedel-Crafts acylation

Answer 1

The correct option is D Friedel-Crafts alkylation and Friedel-Crafts acylation
