Did you hear about the new chemistry class they're offering?

Yeah, I heard it's really interesting, especially the part about substituent groups.

I wonder how much it will help us understand chemical reactions better.

Definitely! Understanding substituent effects can really change how we view compounds.

That's interesting! What did you find out?

Well, it turns out that the position of a substituent can really change how the molecule behaves.

Root Explanation

Substituent → It is formed from "sub-" (meaning under or below) and "stituere" (meaning to place or set). The word refers to something that is placed under or in place of another, particularly in chemistry where it denotes an atom or group that replaces another in a compound.

Memory Tip

Think of something being 'placed under' ('sub-') or 'in place of' ('stituere') another, which helps you remember that a substituent is something that takes the place of another.
