6.7 Bond Enthalpies
A student investigates the relationship between bond order, bond length, and bond enthalpy for the carbon-carbon bonds in ethane (\(\text{C}_2\text{H}_6\)), ethene (\(\text{C}_2\text{H}_4\)), and ethyne (\(\text{C}_2\text{H}_2\)). Which of the following correctly ranks the carbon-carbon bond enthalpy from greatest to least, and provides the correct justification?
