2. (2) Number the carbon
3. (3) Name and number the substituent

If the molecules have the multiple substituents, the compound named as di, tri, tetra, penta, ect.

If the molecules having functional group, the name of the compound is given below. Numbering should be starts from the functional group of the given molecule.

The given compound is an alcohol $\left(\text{OH}\right)$, the compound name end up with ol. The name of the compound is given according to the number of carbon atom.

Example is given below

The given compound is an acid ( $\text{COOH}$), the compound name end up with oic. The name of the compound is given according to the number of carbon atom.

The amides are derivatives of acids and it is named as the ending of alkane with amide.

For example

If the molecule is ester,

Esters end with “ate”
