Hydrocarbon / hydrocarbon definition

WHAT IS HYDROCARBON

A number of chemical compounds is present in the chemistry world, there is approximately 17 million total compounds but not all these compound is same with respect to the nature, so all these compound is different from one another in properties and origin,
Before the 1824 all the chemist belief that the organic compound is only obtained from living things, which explain by Berzelius in 1816 called vital force theory.
This theory say that the organic compound is only obtained from living things.
Finally, this is discarded by Fredrick wholer in 1824 first to synthesis the oxalate ion in lab, but oxalate is not much important compound, after this the urea is prepared in lab from inorganic substance, which is globally accepted, hence the organic compound is defined as " the compound which obtained from living things as well as synthesis in lab is called organic compound".
The hydrocarbon is the parental organic compound because all the organic compound is derived from the hydrocarbon which called derivative of hydrocarbon
There is very huge number of organic compound which is round about 9 million organic compounds.
We know that not all these hydrocarbons is same because the hydrocarbon is formed according to the ratio between the carbon and hydrogen. This anomalous behavior is appearing due to the nature of carbon atom. For example alkane, alkene, alkyne, benzene. In all these the ratio between the carbon and hydrogen atom, like in alkane the ratio is 1:4, which is different from than alkene 1:2.
The hydrocarbon is present in very vast variety due to the stable bond forming between the carbon and carbon atom which is appeared in the form of isomerism. It means hydrocarbon is variable with respect to the composition and structure. Hence, hydrocarbon is present in different structure like open chain and cyclic form.
Further the hydrocarbon is present in different bonding pattern. The hydrocarbon in which the extra absorbing capacity of small molecules is called unsaturated hydrocarbon. Example alkene and alkyne. While other in which no more absorbing capacity of small molecules is called saturated hydrocarbon. Example alkane
