Vedclass · Answer

(B) The reaction involves the treatment of ($1$-hydroxycyclopentyl)methyl bromide with aqueous $AgNO_3$.$1$. The $Ag^+$ ion acts as a Lewis acid and coordinates with the bromine atom,facilitating the departure of the bromide ion $(Br^-)$ to form a carbocation at the $CH_2$ group.$2$. The hydroxyl group $(-OH)$ at the adjacent carbon atom can then participate in a ring expansion rearrangement. The bond between the ring carbon and the adjacent $CH_2$ group migrates to the carbocation center.$3$. This process expands the five-membered ring into a six-membered ring,resulting in a cyclohexyl cation with a hydroxyl group attached to the same carbon.$4$. Subsequent loss of a proton $(H^+)$ from the oxygen atom leads to the formation of cyclohexanone as the stable product.Therefore,the major product is cyclohexanone.

($1$-hydroxycyclopentyl)methyl bromide + $aq. AgNO_3$ $\rightarrow$ ?
