Formula for Alkanes, Alkenes and Alkynes


Organic Chemistry formulas:

Alkanes, alkenes and alkynes are three classes belonging to the hydrocarbon homologues series. These are organic compounds that are composed of carbon and hydrogen as their name implies.

Alkanes have only single bonds, and are therefore saturated hydrocarbons. Their formula is CnH2n+2. Thus, for example four carbon alkane will be C4H 2(4)+2 = C4H10

Alkenes are unsaturated because they have a double bond. Their formula is CnH2n. Thus, for example four carbon alkene will be C4H 2(4) = C4H8.

Alkynes are unsaturated because they have a triple bond. Their formula is CnH2n-2. Thus, for example four carbon alkyne will be C4H 2(4)-2 = C4H6.
