The correct order of increasing bond length of ${\rm{C}} - {\rm{H}},{\rm{C}} - {\rm{O}},{\rm{C}} - {\rm{C}}$ and ${\rm{C}} = {\rm{C}}$ is:

${\rm{C}} - {\rm{H}} < C = C < C - O < C - C$

${\rm{C}} - {\rm{H}} < C - O < C - C < C = C$

${\rm{C}} - {\rm{C}} < C = C < C - O < C - H$

${\rm{C}} - {\rm{O}} < C - H < C - C < C = C$

The correct order of increasing bond length of

\mathrm{C} - \mathrm{H},\mathrm{C} - \mathrm{O},\mathrm{C} - \mathrm{C}

and

\mathrm{C} = \mathrm{C}

is:

View answer and explanation

Correct option: B

\mathrm{C} - \mathrm{H} < C = C < C - O < C - C

Option B (

\mathrm{C} - \mathrm{H} < C = C < C - O < C - C

) is correct because single bonds are longer than double bonds, and bond length increases with the size of the atoms involved.
