nitrogen, sulphur, phosphorus, halogens etc.
Let us see the compounds of carbon with other elements.

Functional groups in carbon compounds

The characteristic properties of an organic compound depend mainly on an atom or group of atoms in its molecule known as the functional group.

Organic compounds are classified by the type of functional group they contain. Functional groups are responsible for the behavior of the organic compounds. Compounds containing the same functional group undergo similar types of reactions.

Carbon compounds with C, H, X.
These are known as halogen derivatives of hydrocarbons or halo hydrocarbons.

Carbon compounds with C, H, O.

Halo Hydrocarbons
Alcohols
If a hydrogen atom of H2O molecule is replaced by 'R' we get alcohols R-OH.

The hydrocarbons that contain-OH group are called alcohols. Observe the following examples:


General formula of alcohols is R-OHwhere'R'

Aldehydes
The hydrocarbons with functional group-CHO are called aldehydes. Observe the following examples:


General formula of aldehydes is R-CHO, where R = alkyl group or hydrogen and -CHO is functional group.
