    See Bond length is inversely proportional to Bond strength or Bond stability. Here Single bond between C & H is very strong as both have small atom radii & formation of bond with H is through 1s which is very strong bond. Now the double bond between C & C has more bond length because they are through outer 2p orbital electrons which are less shielded than 1s-2p than 2p-2p bond. Thus the bond being much stronger between C- H than C=C.

    For this we compare saturated and unsaturated compounds... As the bond order increases 1 in ethane ,2 in ethene ,3 in ethyne Bond strength increases So bond length decreases...So triple bond has less bond length than double bond than single bond
