The reaction of compound P with `CH_3MgBr` (excess) `(C_2H_5)_2O` foll

1.	The reaction of compound P with `CH_3MgBr` (excess) `(C_2H_5)_2O` followed by addition of `H_2O` gives Q. The compound Q on treatment with `H_2SO_4` at `0^@C` gives R. The reaction of R with `CH_3COCl` in the presence of anhydrous `AlCl_3` in `CH_2Cl_2` followed by treatment with `H_2O` produces compound S. [Et in compound P is ethyl group ] The reactions , Q to R an R to S areA. Aromatic sulfonation and Friedel-Crafts acylationB. Friedel-Crafts alkylation and Friedel-Crafts acylationC. Friedel-Crafts alkylation , dehydration and Friedel-Crafts acylationD. Dehydration and Friedel-Crafts acylation
Answer» Correct Answer - B Process involved in Q `to` R reaction is alkylation Process involved in R `to` S reaction is acylation
