When naming an organic compound with more than one substituent, how do you know which one is placed first in the name?

It goes in alphabetical order!

Adding on to the previous post, a good summary of naming organic compounds:

1. You want your substituents (R groups) in alphabetical order
2. You want to achieve the lowest numbers in describing the chemical structure of the organic compound

One thing to remember when listing the substituents alphabetically is that no matter the prefix placed in front of the substituent, they are still listed in alphabetical order. In simpler terms, the prefix does not affect the listing order of substituents.
