How does the basis of the structures of molecules relate to the residual entropy?

[Katarina Povinec 1G]

Molecules with more planes of symmetry will have less entropy because they have less microstates. Think about if you were to draw the structures out, how many planes of symmetry/positions each one would be able to have. The ones with the most would have the least entropy. Also, entropy is a measure of disorder, so if the structure is perfectly symmetrical, changing its orientation or looking at it from a different plane won't lead to more disorder.
