Vedclass · Answer

(D) The debromination of $meso-2,3-dibromobutane$ proceeds via an $E2$ mechanism,which is stereospecific. In the $meso$ form,the two bromine atoms are anti to each other in the staggered conformation. Elimination of $Br_2$ from this conformation leads to the formation of $trans-2-butene$. $trans-2-butene$ is more stable than $cis-2-butene$ due to reduced steric hindrance between the methyl groups.

During the debromination of $meso-2,3-dibromobutane$,the major compound formed is:
