Question

Write the IUPAC name of Benzyl ethyl ether?

Answer 1

Hint: Chemical compounds are classified based on the groups present in them. The classification is known as functional group classification. Ethers are one of the functional groups, consisting of $RO{R}^{\prime }$ . The IUPAC name of benzyl ethyl ether will be written as the derivative of benzene.

Complete answer:
Ethers are one of the functional groups, consisting of Carbon, Hydrogen, and Oxygen atoms. The general molecular formula of ethers is $RO{R}^{\prime }$, where $R$ is an alkyl group, and $R^{\prime }$ is a different alkyl group. Sometimes, both the alkyl groups are the same, and sometimes the two alkyl groups will be different.
Given compound is Benzyl ethyl ether which means it is an ether compound, consisting of an Oxygen atom attached to the Benzyl group on one side and an ethyl group on the other side.
The structure of benzyl ethyl ether is $C_6{H}_{5}C{H}_{2}OC{H}_{2}C{H}_3$
Benzyl group means $C_6{H}_{5}C{H}_2-$ and ethyl group means $-C{H}_{2}C{H}_3$
The IUPAC naming of ethers can be written in terms of benzene derivative. The ethoxy group is substituted in place of one hydrogen atom in the methyl group present on benzene.
The common name of ethers can be written as alkyl alkyl ethers.
Therefore, the IUPAC name of Benzyl ethyl ether is (ethoxy methyl) Benzene.

Note:
The common name of Ethers can be written as Alkyl alkyl ethers, when two same alkyl groups are present, then the ether can be named as dialkyl ether. If the two alkyl groups were different, then the group which comes first in alphabetical order should be written first.
