It's been awhile since I took chemistry, what is the precise definition of 'organics' in this article?
This means hydrocarbons that lack highly stable cyclical structures (e.g. benzene rings). Examples include alkanes, alkenes, alkynes like propane, ethylene, propylene, cyclohexane, etc.
What is special about lacking stable cyclical structures in this context? Does this have any bearing on, say, a link to life?
