Vedclass · Answer

(C) The bond length of a $C-H$ bond depends on the hybridization of the carbon atom. As the $s$-character in the hybrid orbital increases,the electronegativity of the carbon atom increases,pulling the electrons closer to the nucleus and shortening the bond length. $C_2H_2$ has $sp$ hybridization ($50\% \ s$-character),$C_2H_4$ has $sp^2$ hybridization ($33.3\% \ s$-character),and $C_2H_6$ has $sp^3$ hybridization ($25\% \ s$-character). Since $sp^3$ hybridized carbon has the least $s$-character,the $C-H$ bond in $C_2H_6$ (ethane) is the longest.

The $C-H$ bond length is longest in which of the following?
