Vedclass · Answer

(B) The conversion of ethylbenzene $(C_6H_5CH_2CH_3)$ to styrene $(C_6H_5CH=CH_2)$ requires a two-step process: halogenation followed by dehydrohalogenation.Step $1$: Free radical chlorination at the benzylic position using $SO_2Cl_2$ (sulfuryl chloride) yields $1$-chloroethylbenzene $(C_6H_5CHClCH_3)$.Step $2$: Dehydrohalogenation of $C_6H_5CHClCH_3$ using alcoholic $KOH$ (a strong base) leads to the elimination of $HCl$ to form styrene $(C_6H_5CH=CH_2)$.

Which of the following sequence of reactions (reagents) can be used for the conversion of $C_6H_5CH_2CH_3$ into $C_6H_5CH=CH_2$?
