Isopropyl has the specific orientation of being attached to a central carbon atom with two CH3 molecules attached (so in IUPAC naming it can become dimethylethyl), whereas propyl is three carbons all attached in a line branching off the main carbon chain, so it's two CH2 molecules and one CH3 molecule.

The substituent isopropyl has distinct "Y" shape, and the propyl substituent is just a jagged line of CH2CH2CH3.

In the attached picture, the first is the propyl substituent and the second is the isopropyl substituent.

Should we always just use the IUPAC naming instead of the common names?

Lavelle said we would need to know both the IUPAC and Common Names so I'm assuming he'll want us to use the common names when applicable.
