Closed Chains (continued)
Closed or alicyclic carbon chains can be classified in many ways, as can open chains.
Can be classified according to saturation:
- saturated: chain that has only simple bonds between atoms.
- unsaturated: chain having a double carbon bond.
They may be classified according to the presence or absence of a heteroatom:
- homogeneous or homocyclic: have only carbon atoms bonded together.
- heterogeneous or heterocyclic: have a heteroatom between carbon atoms.
The mixed carbon chains are open as well as closed.
