Vedclass · Answer

(D) The reaction is an intramolecular Friedel-Crafts alkylation. $1$. The Lewis acid $AlCl_3$ reacts with the alkyl chloride to form a carbocation intermediate at the secondary carbon. $2$. The benzene ring is substituted with a $-OCH_3$ group (activating,ortho/para directing) and a $-NO_2$ group (deactivating,meta directing). $3$. The $-OCH_3$ group is a stronger directing group than the $-NO_2$ group. $4$. The ortho position relative to the $-OCH_3$ group is sterically hindered,so the cyclization occurs at the para position relative to the $-OCH_3$ group (which is ortho to the $-NO_2$ group). $5$. The resulting product is a substituted tetralin derivative as shown in option $D$.

The major product '$P$' formed in the given reaction is:
