Vedclass · Answer

(A) The reaction of $1$-methoxy$-3-$($2$-methoxyethyl)benzene with excess $HI$ at high temperature involves the cleavage of both ether groups.$1$. The first $S_{N}2$ reaction occurs at the primary alkyl group of the side chain,where the methoxy group is protonated and then attacked by the iodide ion $(I^-)$ to form an alcohol and $CH_3I$.$2$. The second $S_{N}2$ reaction occurs at the methyl group attached to the phenolic oxygen,where the methoxy group is protonated and then attacked by the iodide ion to form phenol and $CH_3I$.$3$. The third $S_{N}2$ reaction involves the conversion of the primary alcohol formed in the first step into an alkyl iodide by reaction with $HI$.Thus,there are a total of $3$ $S_{N}2$ reactions involved in the complete conversion.

The total number of $S_{N}2$ (nucleophilic substitution bimolecular) reactions involved in the following reaction sequence is
