Question

Quizplus · Accepted Answer

Single covalent bonds involve sharing of only one pair of electrons between two atoms. The bond length increases with decreasing bond strength, and the bond strength decreases with the number of shared electrons. Since single bonds have the weakest bond strength, they are the longest. Double and triple bonds involve sharing of two and three pairs of electrons, respectively, and are shorter than single bonds. Therefore, the longest covalent bond between the same two atoms is a single bond.
