In Section 5.6, we learned that triple bonds are stronger and shorter than single bonds. For example, a C-CC-C single bond has an average bond energy of 347 kJ/molekJ/mole, while a C≡CC≡C triple bond has an average bond energy of 837 kJ/molekJ/mole. Use valence bond theory to explain why a triple bond is not simply three times as strong as a single bond.

Answer:the strength of a bond depends on the amount of overlap between the atoms.

Explanation:the greater the overlap the greater the strength of the bond.
