Write the IUPAC name of each of the following:

${\mathrm{CH}}_3\mathrm{CHO}$

Answer 1

Step 1: Introduction

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.

Step 2: Determination of the word root:

This compound contains two Carbon $\left(\mathrm{C}\right)$ atoms.

So, the word root of the compound is “Eth”.

Step 3: Determination of functional group:

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

This compound contains $-\mathrm{CHO}$ group attached to an alkyl group.

So, The functional group of the compound is aldehyde. So, the suffix is “al”

Add all the terms as Eth + ane + al.

Hence, the IUPAC name of the compound is Ethanal.
