### Knowing what has a higher heat capacity

Without doing any calculations, how do we know that ethane has a higher heat capacity than ethene? This was one of the questions in practice problems, but I am not sure how we can automatically come to that conclusion.

Ethane (C2H6) has a higher heat capacity than Ethene (C2H4) because it has only single bonds connecting the carbons, not double bonds, so using the equipartition theorem we can see that there are more DOF which gives it a higher heat capacity.

What is the equipartition theorem?
