I'm just in a simple high school Chem 30-1 class, so yeah. The semester just started, but I'm having trouble with the beginning concepts already.
I've read the stuff, done the work, but it just. doesn't. click.

I'm going in for help tommorow after school, but I'm wondering if anyone knows a good site or some simple explanation for:

ALKANES, ALKENES, AND ALKYNES.

I can't name them, I can't draw them (structurally, cyclo-ically, molecularly (word?)) and I really don't understand them.
It just goes "foosh".

Thanks.

B.

Quite simply, the name represents the number of bonds in carbons in the hydrocarbon.

An alkane has one bond between the carbons, an alkene has two, and the alkyne has three. This is all introductory organic, so any site along those lines should help.

chemhelper.com has a tutorial section that might benefit you.
