Question

Assertion: $IUPAC$ name of the compound is


$2-\text{ethoxy}-2-\text{methylethane}$

Reason: In $IUPAC$ nomenclature, ether is regarded as a hydrocarbon derivative in which a hydrogen atom is replaced by $-OR$ or $-OAr$ group $[\text{where}R=\text{alkyl group and}Ar=\text{aryl group}]$

Answer 1

Explaining the assertion

The $IUPAC$ name of the ether family is $‘{\text{alkoxyalkane}}^{\prime },$ where the $‘{\text{alkane}}^{\prime }$ part is the longest principal chain.

The $IUPAC$ name of the given compound is $2-\text{propoxypropane.}$
The $IUPAC$ name of the given compound can also be $1-\text{isopropoxypropane.}$
So, the assertion is an incorrect statement.

Reason:
In $IUPAC$ nomenclature, ether is regarded as a hydrocarbon derivative in which a hydrogen atom is replaced by $-OR$ or $-OAr$ group $[\text{where}R=\text{alkyl group and}Ar=\text{aryl group}].$
The reason is a correct statement.

Hence, the assertion is an incorrect statement, but the reason is a correct statement.
