When Alkynes Are Called Acetylenes?

UNSATURATED alkyne hydrocarbons contain triple bonds

triple bonds
Triple bonds are stronger than the equivalent single bonds or double bonds, with a bond order of three. The most common triple bond, that between two carbon atoms, can be found in alkynes. Other functional groups containing a triple bond are cyanides and isocyanides.

. Since the compound is unsaturated with respect to hydrogen atoms, the extra electrons are shared between 2 carbon atoms forming double bonds. Alkynes are also generally known as ACETYLENES from the first compound in the series.

Why is alkynes called unsaturated?

Like alkenes, alkynes are unsaturated because they are capable of reacting with hydrogen in the presence of a catalyst to form a corresponding fully saturated alkane. Each π bond signals that two hydrogen atoms have been lost from the molecular formula of the alkane with the same number of carbon atoms.

What are alkynes also called?

major reference. In hydrocarbon: Alkenes and alkynes. Alkenes (also called olefins) and alkynes (also called acetylenes) belong to the class of unsaturated aliphatic hydrocarbons. Alkenes are hydrocarbons that contain a carbon-carbon double bond, whereas alkynes have a carbon-carbon triple bond.
