Why doesn tthe molecular formula for Freon(Dupont TM) follow the Hill System for order of atoms?
from what I can find, fluorinated alkanes calculate the formula from right to left. I can t find out why they differ. Normally molecular formulae(eg H2O) put C first, if present, then H, if present, then alphabetical (eg H2O4S for Sulphuric acid, when written with correct nomenclature)

You can order the atoms any way you like. You can choose to use the Hill System or not. If you don't use Hill, then it's usually C first, with the rest in alphabetical order by symbol, with a few conventional exceptions.
