Vedclass · Answer

(A) The conversion of $3-$vinylbenzaldehyde to $3-(2-$bromoethyl$)$benzoic acid involves two main transformations: $1$. Oxidation of the aldehyde group $(-CHO)$ to a carboxylic acid group $(-COOH)$ using the iodoform test reagents $(I_2/NaOH)$ which selectively oxidizes the methyl ketone or aldehyde group while leaving the alkene intact. $2$. Anti-Markovnikov addition of $HBr$ to the vinyl group $(-CH=CH_2)$ using $HBr/R_2O_2$ (peroxide effect) to yield the $2-$bromoethyl substituent. Thus,the correct sequence of reagents is $I_2/NaOH$ followed by $HBr/R_2O_2$.
