since an optically active alkene upon hydrogenation gives optically inactive alkene, alkane has two indentical groups, i.e, ( mathrm{C}_{2} mathrm{H}_{5} ) groups while alkene has one vinyl ( left(mathrm{CH}_{2}=mathrm{CH}right) ) and one ethyl 1 Thus the structure of alkene is 3 -methyl-1 -pentene.
