We were doing the topic "Isomerism" in our Organic Chem class and there's a question in our worksheet whose answer I haven't really understood, the question is as follows:
The racemization of optically active compounds is driven by? (a): Entropy (b): Enthalpy (c): Entropy and Enthalpy (d): Element of Symmetry
The worksheet answer key says the answer is (a): Entropy. But I wasn't so sure of this answer, although I could rule out that it isn't (d) for sure since, for an optically active compound, there shouldn't be an element of symmetry (or it would be Inactive). But I can't quite understand why the answer should be Entropy, I always thought entropy just means the degree of randomness like particles just vibrating.
It would be of great help if you could tell me if the answer is in fact Entropy; and if so, could you perhaps explain how Entropy would influence this optical activity.
Thank you for your time!
