Bond length is the measurable distance between two covalently bonded atoms. This measurable distance is an average, as the distance between atoms bounded together can change. Electrostatic forces, where opposites attract, contribute to the strength of a bond.
In benzene all bonds have the same length: 139 pm. Carbonâcarbon single bonds increased s-character is also notable in the central bond of diacetylene (137 pm) and that of a certain tetrahedrane dimer (144 pm). In propionitrile the cyano group withdraws electrons, also resulting in a reduced bond length (144 pm).
