Isopropyl vs Propyl [ENDORSED]

[904779609]

What is the difference between isopropyl and propyl?????

[Marie_Rhoads_2C]

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.

[Vivian Tan 3F]

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?

[Shailyn_Moore_3C]

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.
