An alkyne is an unsaturated hydrocarbon with at least one carbon-carbon triple bond in organic chemistry. Alkynes are unsaturated hydrocarbons with one triple bond; their usual formula is CnH2n-2, and the triple bond is referred to as the ‘acetylenic bond.’ Alkynes can be found in abundance in nature.
Acetylene
Acetylene (synonym: ethyne) is a hydrocarbon that belongs to the alkyne family. Because it just has two hydrogen atoms and two carbon atoms, it is considered the most basic of all alkynes. As it has four atoms which are triple linked through a covalent connection, acetylene is an unsaturated organic molecule.
The carbon-carbon triple bond gives the carbon atoms two sp hybrid orbitals for sigma bonding, putting all four atoms in a straight line with 180° CCH bond angles.
Properties of Acetylene:
- Acetylene (C2H2) is a volatile and colorless gas.
- Acetylene is odorless at 100 percent pure, but it has a garlic-like odor at commercial purity.
- Acetylene is easily liquefied and solidified, yet when ignited, it bursts with great force in both circumstances.
- Acetylene can be ingested in high doses without causing long-term harm.
- It’s a type of anesthesia.
- If present in amounts high enough to deprive the lungs of oxygen and cause suffocating, it is a simple asphyxiate.
