Vedclass · Answer

(B) The reaction involves the treatment of bromobenzene with a dichloroalkane in the presence of $AlCl_3$. This is an intramolecular Friedel-Crafts alkylation reaction. The electrophile generated from the alkyl chloride attacks the benzene ring. Given the structure of the reactant,the cyclization leads to the formation of a tetrahydronaphthalene derivative. The correct product is $1$-bromo-$5,5$-dimethyl-$5,6,7,8$-tetrahydronaphthalene.
