C2H4N2

C2H4N2 is the chemical formula for several different compounds, all of which are isomers. The most common compound represented by this formula is diazene, also known as dinitrogen. Diazene is an unstable molecule consisting of two nitrogen atoms double-bonded to each other, with each nitrogen atom also bonded to a hydrogen atom. It exists as cis and trans isomers.

Another isomer with the formula C2H4N2 is methyl isocyanide. This molecule has a carbon atom triple-bonded to a nitrogen atom, and a methyl group (CH3) single-bonded to the carbon. This arrangement results in a different connectivity of atoms compared to diazene.

A third possible isomer is cyclobutadiene-1,2-diimine. This is a cyclic compound containing a four-membered ring with two nitrogen atoms and two carbon atoms. The arrangement and bonding within this ring structure differ significantly from the linear or branched structures of diazene and methyl isocyanide.

Due to their instability and reactivity, some of these isomers are not commonly encountered or are primarily studied in specialized chemical research. The properties and applications of compounds with the formula C2H4N2 are diverse and depend entirely on the specific isomeric structure.
