Alkynes

General formula
CnH2n-2

Aliphatic hydrocarbons with one triple bond between carbons are called alkynes. They follow the naming convention of the alkanes except that the suffix -yne is used instead of -ane. For alkynes above propyne the position of the double bond must be specified in the name.

ethyne
acetylene
propyne
Alkynes are unsaturated hydrocarbons and are generally very reactive. Typical reactions involve the addition of hydrogens or halogens.

Ethyne

The simplest of the alkyne series, it is commonly called acetyline. It is often used as a fuel for welding torches sinces it produces a large amount of heat upon combustion. Oxyacetylene welding uses compressed acetylene and compressed oxygen for mixing in the torch flame.
