| Alkene | |
Alkanes are saturated hydrocarbons with general formula: CnH2n+2 | Alkenes are unsaturated hydrocarbons with general formula: CnH2n or CnH2n−2 | |
In these hydrocarbons, the carbon atoms are linked to each other by single covalent bonds. e.g., C2H6 | In these hydrocrbons, the valencies of carbon atoms are bot satisfied by single covalent bond. e.g., C2H4,C2H2 |
