Question

Identify the functional group present in ${\mathrm{CH}}_3\mathrm{OH}$ and write its IUPAC name

Answer 1

The functional group is an atom or group of atoms that are responsible for the characteristic of the particular compound.

The IUPAC name of the compounds is the proper rules to naming the organic compounds. It is assigned by the International Union of Pure and Applied Chemistry.

Determination of functional group

The organic compound which have $-\mathrm{OH}$ group. So, that organic compound has functional group of alcohol.

${\mathrm{CH}}_3\mathrm{OH}$ compound contains $-\mathrm{OH}$ group attached to an alkyl group. So, its functional group of the compound is Alcohol.

Determination of IUPAC name

The compound has one Carbon $\left(\mathrm{C}\right)$atom so the word root is “Meth”.

The compound is saturated in nature So, pre suffix is “ane”.

The compound has a functional group of alcohol. So, the suffix is “ol”

Add all the terms as Meth + ane + ol.

So, the IUPAC name is Methanol.
