IPA: //ˈdaɪəzaɪn//
KK: /ˈdīəˌzēn/
A chemical compound that has a benzene ring with two of its carbon atoms replaced by nitrogen atoms, particularly referring to any of the three isomers with the formula C4H4N2.
Diazine is used in various chemical reactions and applications in organic chemistry.
Diazine is formed from "dia-" (meaning through or across) and "azine" (a suffix used in chemistry to denote a class of compounds containing nitrogen). The word refers to a class of organic compounds that contain two nitrogen atoms in a six-membered ring structure, thus indicating a compound that has nitrogen atoms across its structure.
Think of 'dia-' meaning 'across' and 'azine' relating to nitrogen compounds, which helps you remember that 'diazine' refers to a compound with nitrogen atoms arranged across its structure.
