In chemistry, any of several hydrocarbons containing seven carbon atoms and one triple bond between two carbon atoms.
From Greek 'hepta' (seven) + the chemical suffix '-yne' (or '-ine,' indicating a triple bond in hydrocarbons), literally 'seven-carbon alkyne.'
Heptine has three different structural arrangements (isomers) in its seven carbons—it's a perfect example of how identical atoms arrange themselves into utterly different molecules!
