A structure is an arrangement and organization of interrelated elements in a material object or system, or the object or system so organized. Material structures include man-made objects such as buildings and machines and natural objects such as ...
. It is an
alkyl
In organic chemistry, an alkyl group is an alkane missing one hydrogen.
The term ''alkyl'' is intentionally unspecific to include many possible substitutions.
An acyclic alkyl has the general formula of . A cycloalkyl group is derived from a cy ...

propyne
Propyne (methylacetylene) is an alkyne with the chemical formula . It is a component of MAPD gas—along with its isomer propadiene (allene), which was commonly used in gas welding. Unlike acetylene, propyne can be safely condensed.Peter Pä ...
().
The term propargylic refers to a
saturated position (
''sp''3-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
