Which order is correct for bond length-

Options

A. `-=C -G gt -C - G gt = C-H`
B. `-C-H lt -=C-H lt =C-H`
C. `-=C-H lt =C-H lt -C-H`
D. none of these

Answer

C

Explanation

As bonding atom's s-character increases bond length decreases and bond strength increases
`-=overset(sp)(C)-overset(s)H lt =overset(sp^(2))(C)-overset(s)(H) lt - overset(sp^(3))(C)- overset(s)(H)`
