Vedclass · Answer

(B) The bromination of $trans-2-butene$ is an anti-addition reaction. When $Br_2$ adds to $trans-2-butene$,the two chiral centers formed have opposite configurations due to the anti-addition mechanism. This results in the formation of a racemic mixture of $(2R, 3R)-2,3-dibromobutane$ and $(2S, 3S)-2,3-dibromobutane$. Since these two are enantiomers,they constitute $2$ stereoisomers. Therefore,the correct option is $(B)$.
