Vedclass · Answer

(D) Styrene $(C_6H_5CH=CH_2)$ is prepared from benzene $(C_6H_6)$ in two steps:$1$. Ethylbenzene is prepared by the alkylation of benzene with ethene in the presence of an $AlCl_3$ catalyst: $C_6H_6 + CH_2=CH_2 \xrightarrow{AlCl_3} C_6H_5CH_2CH_3$.$2$. Ethylbenzene is then dehydrogenated at high temperature $(700^{\circ}C)$ using a catalyst (typically iron oxide or $Al_2O_3$) to produce styrene: $C_6H_5CH_2CH_3 \xrightarrow{700^{\circ}C, 	ext{catalyst}} C_6H_5CH=CH_2 + H_2$.

Which one of the following is used in the preparation of styrene?
