Vedclass · Answer

(C) The reaction involves the electrophilic addition of $HBr$ to the alkene. The starting material contains a chiral center. Upon protonation of the double bond,a carbocation is formed at the $C-2$ position. The subsequent attack of the bromide ion $(Br^-)$ can occur from either side of the planar carbocation,leading to the formation of two new chiral centers. Since the molecule already possesses one chiral center,the formation of a second chiral center results in the creation of two diastereomeric products. These products are not mirror images of each other and are therefore diastereomers.
