propyl
Definition
- Noun:
- The monovalent organic group C₃H₇⁻ obtained from propane: In organic chemistry, "propyl" refers to a specific alkyl group (a substituent) derived from propane by removing one hydrogen atom. It has the chemical formula -C₃H₇ and is a three-carbon chain attached to another molecule.
Examples of Usage
- Noun:
- The compound contains a propyl group attached to the nitrogen atom.
- Propyl alcohol, also known as 1-propanol, has the propyl group bonded to a hydroxyl group.
Advanced Usage
- Chemical Nomenclature: "Propyl" is used systematically in IUPAC names to indicate the presence of this three-carbon alkyl substituent. For example, "propylbenzene" is benzene with a propyl group attached.
- Isomer Distinction: The term "propyl" typically refers to the -propyl (normal-propyl) isomer, which is a linear chain. The branched isomer is specifically called "isopropyl."
Variants and Related Words
- Isopropyl (noun): The branched isomer of the propyl group, with the formula (CH₃)₂CH⁻.
- Isopropyl alcohol is a common disinfectant.
- Propylene (noun): An unsaturated hydrocarbon (C₃H₆), also known as propene, which is related as it is the source of many propyl-containing compounds.
- Propane (noun): The parent alkane (C₃H₈) from which the propyl group is formally derived.
Synonyms
- n-Propyl: A more precise synonym used in scientific contexts to distinguish the linear isomer from isopropyl.
- C₃H₇ group: A formula-based synonym used in chemical notation.
Related Phrases and Terms
- Propyl group: The most common phrase, used to specify the substituent in a molecular structure.
- Propyl derivative: A compound formed by introducing a propyl group into another molecule.
Noun
-
the monovalent organic group C3H7- obtained from propane
