Chemistry - CHEMICAL BONDING Question with Solution | TestHub

TheC−Hbond is the shortest due to the small size of both atoms & large electronegativity difference.
The double bonds are shorter than single bonds.
HenceC=C<C−OandC−C
Due to electronegativity difference betweenCandO
C−O<C−C
Increasing order of bond length is
$\underset{107\mathrm{p}\mathrm{m}}{\mathrm{C}-\mathrm{H}}<\underset{134\mathrm{p}\mathrm{m}}{\mathrm{C}=\mathrm{C}}<\underset{141\mathrm{p}\mathrm{m}}{\mathrm{C}-\mathrm{O}}<\underset{154\mathrm{p}\mathrm{m}}{\mathrm{C}-\mathrm{C}}$
