Answer: From the equipartition theorem, ethane has more degrees of freedom than ethene and therefore will have a higher heat capacity.

What are the degrees of freedom as it relates to ethane and ethene ? How is this calculated?

Is the degrees of freedom related to how many single and double bonds there are in the molecule?
