I am very confused about how to tell which molecule is a substituent or what a substituent even means or why it is relevant in naming. Could someone explain a substituents's purpose? Thank you!

A substituent is a group that's attached to one of the carbons in the longest parent carbon chain in the molecule. Substituents are important because they play a huge role in determining the properties of the molecules.

Is the number of substituents limited to the number of carbons on the parent chain?

I think you are right. A substituent is an atom or group of atoms that replaces hydrogen atoms on the parent chain of a hydrocarbon so I think from what we've talked about so far the number is limited to the number of carbons on the parent chain.

Theoretically, you can add as many substituents as you have hydrogens on a carbon chain, so you could have like 14 methyl substitutes on a C6H14 hydrocarbon chain. This molecule probably does not exist, since the repulsive forces between the hydrogen atoms and the bond angles would be a mess, but as far as we know right now, this could happen.
