网页Starting with a three carbon alkyl group (propyl) the possibility of multiple connection points necessitates connection prefixes. These prefixes are often abbreviated with a letter which is italicized.
Propyl group - Wikipedia
网页In organic chemistry, a propyl group is a three- carbon alkyl substituent with chemical formula −CH2CH2CH3 for the linear form. This substituent form is obtained by removing one hydrogen atom attached to the terminal carbon of propane. [1]
Nomenclature of Alkanes II - Chemistry LibreTexts
网页2023年1月23日 · Substituent names are methyl, ethyl, propyl, butyl, etc. The number showing the point of attachment to the parent chain precedes the substituent name. If you have more than one substituent with the same name, a number of attachment must be given for each substituent and the number of the substituents must be designated with di-, tri-, etc.

网页2019年8月28日 · The IUPAC system requires first that we have names for simple unbranched chains, as noted above, and second that we have names for simple alkyl groups that may be attached to the chains. Examples of …
Propyl Group - Encyclopedia.com
网页The propyl group is one of the alkyl groups defined by dropping the -ane ending from their parent compound and replacing it with -yl. The propyl group is derived from propane (HCH 2 CH 2 CH 3 ) by removing one of the end hydrogens.
Propyl Definition & Meaning - Merriam-Webster
网页The meaning of PROPYL is either of two isomeric alkyl radicals C3H7 derived from propane —often used in combination.

What is the meaning of n-Pr and i-Pr? - Chemistry Stack Exchange
网页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 $\ce{CH3CHXCH3}$).

Alkyl group - Wikipedia
网页Alkyls include methyl, (−CH 3), ethyl (−C 2 H 5), propyl (−C 3 H 7), butyl (−C 4 H 9), pentyl (−C 5 H 11), and so on. Alkyl groups that contain one ring have the formula −C n H 2n−1, e.g. cyclopropyl and cyclohexyl.
