During debromination of meso-dibromobutane, the major compound formed is
$n$-butane
1 -butene
cis-2-butene
trans-2-butene
Solution
In the debromination reaction of meso-dibromobutane, the two bromine atoms leave the molecule and to stabilise the compound forms a double bond. The two products namely cis-but$-2-$ene and $trans-but-2-ene$ formed in the reaction. As trans$-2-$butene is more stable than cis-but$-2-$ene, it is the major product.
