Saturated and unsaturated carbon
- Compounds which are made up of carbon and hydrogen only are known as hydrocarbons.
- There are two types of hydrocarbons
- compound have only single bond between different atoms.
- These compounds are normally not very reactive.
- Examples- alkanes – methane, ethane, propane, hexane
- compound have double or triple bond between different atoms.
- They are more reactive than the saturated carbon compounds.
- Examples- alkenes- ethane, propene, hexane,
- Alkynes- ethyne, propyne, hexyne
Note-Branching, chain and ring
- Example of branching – with four carbon atoms, there are two different possible structures
- As we see in above example compounds with identical molecular formula (C4H10) but different structures are called structural isomers.
- EXAMPLE of ring formation- many hydrocarbons form a ring like structure also known as cyclic hydrocarbon. They may be saturated or unsaturated.
