D
C-C single bond
Verified step by step guidance1
Understand that bond energy is the measure of bond strength in a chemical bond. The higher the bond energy, the stronger the bond.
Recognize that a C≡C triple bond involves three pairs of shared electrons, making it very strong and thus having high bond energy.
A C=C double bond involves two pairs of shared electrons, which is stronger than a single bond but weaker than a triple bond.
An O-H bond is a single bond but involves a highly electronegative oxygen atom, which can make it relatively strong compared to other single bonds.
A C-C single bond involves only one pair of shared electrons, making it the weakest among the options provided, and thus it has the lowest bond energy.
