acetylene
Sign in to saveAcetylene (systematic name: ethyne) is a chemical compound with the formula and structure . It is a hydrocarbon and the simplest alkyne. This colorless gas is widely used as a fuel and a chemical building block. It is unstable in its pure form and thus is usually handled as a solution. Pure acetylene is odorless, but commercial grades usually have a marked odor due to impurities such as divinyl sulfide and phosphine.
AI overview
Acetylene is a colorless gas made of hydrogen and carbon that serves as both a fuel and a key ingredient for making other chemicals. Because pure acetylene is unstable and dangerous to handle, it's typically stored and transported dissolved in a solution, and commercial versions have a strong smell added to help detect leaks.

Acetylene (systematic name: ethyne) is a chemical compound with the formula and structure . It is a hydrocarbon and the simplest alkyne.

Pure acetylene is odorless, but commercial grades usually have a marked odor due to impurities such as divinyl sulfide and phosphine.
As an alkyne, acetylene is unsaturated because its two carbon atoms are bonded together in a triple bond. The carbon–carbon triple bond places all four atoms in the same straight line, with CCH bond angles of 180°. The triple bond in acetylene results in a high energy content that is released when acetylene is burned.
