Differentiate between alkanes and alkenes. Name and draw the structure of one member of each.
The difference between alkanes and alkene are as follows:
Alkane | Alkene |
1. It is a hydrocarbon in which the atmos are connected to each other through a single covalent bond. | It is a hydrocarbon in which the atoms are connected to each other through a double bond. |
2. The general formula of alkanes is: CnH2n+2 | The general formula of alkenes is: CnH2n |
3. They burn in air with blue and non-sooty flame. | They burns in air with a yellow and sooty flame. |
4. Alkanes undergoes substitution reactions. Moreover Alkanes are not able to decolourise the red-brown color of Bromine (Br2) water. | They undergoes addition reactions and not substitution reactions and can decolorise the Red-Brown color of Br2 water. |
One of the member of alkane is: Methane having molecular formula (CH4). The structure of CH4 is as folllows:
One of the member of alkene is Ethene having molecular formula C2H4 and the structure of Ethene is as follows:
