Vedclass · Answer

(B) The catalytic hydrogenation of alkenes using $Ni$,$Pd$,or $Pt$ catalysts involves syn-addition of hydrogen (or deuterium) to the double bond. For $trans-2$-butene,the addition of $D_2$ occurs from the same side (syn-addition). Since the starting material is $trans-2$-butene,the syn-addition of $D_2$ results in the formation of $meso-2,3$-dideuteriobutane. This is because the resulting molecule has a plane of symmetry,making it a $meso$ compound.

What is the product formed when $trans-2$-butene reacts with $D_2$ in the presence of a $Ni$ catalyst?
