, propargyl is an alkyl functional group

Functional group

In organic chemistry, functional groups are specific groups of atoms within molecules that are responsible for the characteristic chemical reactions of those molecules. The same functional group will undergo the same or similar chemical reaction regardless of the size of the molecule it is a part of...

Propynyl

In chemistry, propynyl is an propyl functional group bearing a triple bond. 2-Propynyl is known as propargyl group with the structure of HC≡C−CH2 and 1-propynyl group has the structure of CH3-C≡C-....

 with the structure HC≡C−CH₂−, derived from the alkyne

Alkyne

Alkynes are hydrocarbons that have a triple bond between two carbon atoms, with the formula CnH2n-2. Alkynes are traditionally known as acetylenes, although the name acetylene also refers specifically to C2H2, known formally as ethyne using IUPAC nomenclature...

 propyne.

The term propargylic refers to a saturated position (sp³-hybridized) on a molecular framework next to an alkynyl group. The name comes from mix of "propene" and "argentum" which refers to the typical reaction of the terminal alkynes with silver salts.

The term homopropargylic designates in the same manner

• a saturated position on a molecular framework next to a propargylic group and thus two bonds from an alkyne
