Vedclass · Answer

(C) Bond length is inversely proportional to the $s$-character of the hybrid orbital of the carbon atom.$1.$ In $C_2H_2$ (Ethyne),the hybridization of carbon is $sp$,which has $50 \% \ s$-character.$2.$ In $C_2H_4$ (Ethene),the hybridization of carbon is $sp^2$,which has $33.33 \% \ s$-character.$3.$ In $C_2H_6$ (Ethane),the hybridization of carbon is $sp^3$,which has $25 \% \ s$-character.Since $C_2H_6$ has the lowest $s$-character $(25 \%)$,the $C-H$ bond length is the greatest in $C_2H_6$.
