Our animal services officers will remove dead stray animals and dead wildlife on public property (except freeways). Dead cats and dogs will be checked for micochips.
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.
Shorter than average CâC bond distances are also possible: alkenes and alkynes have bond lengths of respectively 133 and 120 pm due to increased s-character of the sigma 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).
