Vedclass · Answer

(A) The reaction shown is the Hell-Volhard-Zelinsky $(HVZ)$ reaction. In this reaction,carboxylic acids having an $\alpha$-hydrogen atom are reacted with $Br_2$ or $Cl_2$ in the presence of a small amount of red phosphorus to form $\alpha$-halo carboxylic acids. The $\alpha$-carbon is the carbon atom directly attached to the carboxyl group. In cyclopentanecarboxylic acid,the carbon atom of the cyclopentane ring attached to the $-COOH$ group is the $\alpha$-carbon. Therefore,the bromine atom replaces the hydrogen atom at the $\alpha$-position,resulting in $1$-bromocyclopentanecarboxylic acid.
