When you have multiple substituents, do you prioritize the substituents for numbering by size or by alphabetical order? For example, if you have an ethyl and a propyl substituent on a cyclohexane, which one gets priority in numbering?
For substituents like ethyl and propyl, you would only prioritize alphabetically if there's a tie. Otherwise just number them to the lowest number. But for halogens like Cl or Br, you would prioritize by size but still list alphabetically in the name.
