A student determines the melting point of an unknown compound X to be 133-135oC. The student prepares two separate mixtures and determines the melting point of each mixture accordingly:

Cpd X + Benzoic acid 120-126oC
Cpd X + Cinnamic acid 134-136oC
What is the identity of unknown X?

That is not a question which can be answered except empirically, and not exclusively either.

Chemical knowledge does not provide a guide for the "true" answer to that question and whatever anyone says in this thread is bullshit based on a missunderstanding of the physical world operates.
