What is the chemical symbol for acetylene?

Explanation:
Acetylene (also called ethyne) is the simplest alkyne and consists of two carbon atoms connected by a triple bond, with one hydrogen attached to each carbon. That gives the molecular formula C2H2. This fits the general pattern for alkynes, CnH2n-2, so with n = 2 you get H = 2. The other formulas correspond to different compounds: C2H4 is ethene with a double bond, CH4 is methane, and CO2 is carbon dioxide with no hydrogens.
