Vedclass · Answer

(B) The electrophilic addition of $Br_2$ to $trans-but-2-ene$ proceeds via an anti-addition mechanism. When $Br_2$ adds to $trans-but-2-ene$,the two bromine atoms are added to opposite faces of the double bond. This results in the formation of a meso compound,specifically $(2R, 3S)-2,3-dibromobutane$. Since the molecule has an internal plane of symmetry,the product is achiral and optically inactive. Because the addition is anti,the product formed is a single meso compound (which can be represented in different conformations,but they are identical). Therefore,the correct answer is $2$ identical mesomers (representing the same meso compound).

The stereoisomers that are formed by electrophilic addition of bromine to $trans-but-2-ene$ is/are:
