Propyl group - Wikipedia
A propyl group is a three-carbon alkyl substituent with formula −CH2CH2CH3. It has two isomeric forms: n-propyl and isopropyl (or iPr), and a non-isomeric form: cyclopropyl.

What is the meaning of n-Pr and i-Pr? - Chemistry Stack Exchange
Propyl is the unit formed by attaching that chain to something else (which implies replacing one of the carbons with another bond). There are two ways to do this: one attaches the propyl unit using the end carbon on the chain (giving $\ce{X-CH2CH2CH3}$); the other involves attaching the middle carbon to something else (giving $\ce{CH3CHXCH3}$).

Propyl group is a portion of a molecular structure equivalent to propane minus one methyl group hydrogen atom: -CH 2 CH 2 CH 3. It is sometimes abbreviated as Pr and has related terms such as acetyl, alkyl, and benzyl groups.
3.3 Alkyl Groups - Organic Chemistry - OpenStax
Highlights. If you imagine removing a hydrogen atom from an alkane, the partial structure that remains is called an alkyl group. Alkyl groups are not stable compounds themselves, they are simply parts of larger compounds and are named by replacing the - ane ending of the parent alkane with an - yl ending.
