Question

What Is The IUPAC Name Of ${\mathrm{CH}}_3{\mathrm{CH}}_2-\mathrm{O}-{\mathrm{CH}}_2{\mathrm{CH}}_2{\mathrm{CH}}_3$?

Answer 1

IUPAC Nomenclature

• “In order to clearly identify the compound, a systematic method of naming has been developed and is known as the IUPAC (Internation Union of Pure and Applied Chemistry) system of nomenclature.”

Rules of IUPAC nomenclature

• The structure of ${\mathrm{CH}}_3{\mathrm{CH}}_2-\mathrm{O}-{\mathrm{CH}}_2{\mathrm{CH}}_2{\mathrm{CH}}_3$ is as follows,
• 

Determination of Root Word

Select the continuous chain with the maximum number of carbon atoms

Here the chain is having 3 carbon atoms, hence root word will be “Prop”

2: Determination of names and positions of Locants

There is no substituent in the given compound.

3: Determination of Suffix ”

For the ether functional group, alkoxy alkane is used.

• Hence, the IUPAC name of ${\mathrm{CH}}_3{\mathrm{CH}}_2-\mathrm{O}-{\mathrm{CH}}_2{\mathrm{CH}}_2{\mathrm{CH}}_3$ is 1-ethoxypropane.
