### Molecular Complexity

Why do more complex molecules have a higher S (as compared to simple molecules) if they are more ordered and structured?

Because they have more positions or states that the molecule can be in. They have more atoms and are arranged in a more complicated way than less complex molecules.

Entropy at the molecular level means having more 'microstates', or different ways of arranging atoms. Complex molecules have more atoms, and therefore, more places you can change its composition.

### Re: Molecular Complexity

More complex molecules have a higher S because they have a greater amount of rotational and vibrational energies, meaning that they have more possible microstates they can be in, leading to a greater entropy.

### Re: Molecular Complexity

More complex molecules have a higher entropy value due to having an increased number of rotational/positional energies.
