I was wondering if someone could explain to me why more complex molecules have a greater standard entropy value than less complex molecules. Thank you!

A more complex molecule would have a higher delta S because a more complex molecule has more possible vibrations and motions making the entropy greater.

A more complex molecule has more possible positions it may attain (since there are more atoms involved) which is one way we measure entropy.

Would the value of entropy differ based on bond strength as well? Would there be less entropy in a triple bond than in a single bond?

More complex molecules can occupy more microstates so the entropy values are higher.

More complex molecules also have more subatomic fundamental particles, and a higher number of particles always increases degeneracy (unless there is only 1 state in which case W=1). This goes for atoms too, atoms with more mass/higher atomic number have higher entropies

More complex molecules have more "things" or smaller particles in them that give them more micro states to be filled. So therefore being more complex makes them have higher entropy values.
