Answer:
Molar entropy of butane is greater than 2-butene.
Explanation:
Definition:
Entropy content of one mole of pure substance at standard state of pressure and any temperature is called as molar entropy. while the temperature and pressure to be chosen as standard mostly.
So entropy of 2-butene is less because double bond restricts the rotation. And the freedom of atom in 2-butene is less.
