IPA: //ˈdaɪ.iːn//
KK: /ˈdaɪˌin/
A type of organic compound that has two double bonds between carbon atoms.
The chemist synthesized a diene for the experiment.
Diene is formed from the prefix "di-" (meaning two) and the root "ene" (from Greek "ainos", meaning to be or exist, used in chemistry to denote a double bond). The word "diene" refers to a hydrocarbon that contains two double bonds.
Think of 'di-' meaning two, and 'ene' indicating a double bond in chemistry. This helps you remember that a diene is a compound with two double bonds.
