Nomenclature of Alcohol compounds:

The naming of theorganic compound is given by IUPAC (International Union for pure and applied chemistry). In the IUPAC names consist of certain rules for giving chemical names they are,

• The longest chain of Carbon atoms containing the $\text{–OH}$ group is the parent alkane and numbered from the end closer to $\text{–OH}$.
