Question

Acetylene is a unsaturated hydrocarbon

Answer 1

Acetylene (systematic name: ethyne) is the chemical compound with the formula C2H2. It is a hydrocarbon and the simplest alkyne.[5]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.[6] Pure acetylene is odorless, but commercial grades usually have a marked odor due to impurities.[7]

Answer 2

Answer:

As an alkyne, acetylene is unsaturated because its two carbon atoms are bonded together in a triple bond.
