WebFormulae. Alkenes are a family of hydrocarbons (compounds containing carbon and hydrogen only) containing a carbon-carbon double bond. The first two are: ethene. C 2 H 4. propene. C 3 H 6. You can work out the formula of any of them using: CnH2n. The table is limited to the first two, because after that there are isomers which affect the names. WebEven if you don't need to know it, chemical bonds are the most fundamental part of chemistry and it can't hurt to know about them, there's not much that's difficult about them anyway. Sigma bonds are stronger and any time you see a double or triple bond you know there's at least one pi bond in there. A double bond is composed of 1 sigma + 1 pi. A triple …
