* Alkenes: Alkenes are hydrocarbons with a carbon-carbon double bond.
* Decane: Decane is a ten-carbon alkane (only single bonds between carbons).
To get a structural formula, you need to specify the position of the double bond:
* 1-decene: The double bond is between the first and second carbon atoms.
* 2-decene: The double bond is between the second and third carbon atoms.
* 3-decene: The double bond is between the third and fourth carbon atoms.
* ...and so on.
General Formula:
The general formula for an alkene is CnH2n. For decene (n=10), the general formula would be C10H20.
Example: 1-Decene
The structural formula for 1-decene would be:
```
CH2=CH-CH2-CH2-CH2-CH2-CH2-CH2-CH2-CH3
```
Isomers:
Because the double bond can be in different positions, there are many isomers of decene. For example, 1-decene and 2-decene are structural isomers.
