Question

Give the IUPAC name of the compound $C{H_3}OC{H_2}C{H_3}$ is:
A. Dimethyl ether
B. Methoxyethane
C. Methylethyloxide
D. Propyl ether

Answer 1

Hint: In organic chemistry, the naming of the compounds is done according to the standards that are laid by the IUPAC which is the acronym for the International Union of Pure and Applied Chemistry. The compounds are so named as to help the deduction of the structure by just the name of the compound.

Complete step by step answer:
The IUPAC has led to certain rules for the naming of the organic compounds which describe the structure of the compound. The naming according to the standards of the IUPAC is the standard manner of naming a compound but the trivial or the common names are usually preferred as they are much shorter and easy to remember.
The IUPAC name of the compounds has certain rules which include the naming of the functional group at the last and the substituent groups at the start with the position at which they are attached. All this is provided to get the structure of the compound.
The given compound consists of an oxy linkage between the two alkanes, namely methane and ethane. This type of linkage is written as oxy linkage.
According to the IUPAC convention, the name of the smaller group should have to come before the other group which is present after the oxy linkage, so in this case, it would be methyl coming before ethyl.
So, according to the above-mentioned points, the IUPAC name of the compound will be methoxyethane.

So, the correct answer is Option B.

Note: The above compound is categorized under the ether functional group and its name will be ethyl methyl ether. It is a colorless ether.
Various other functional groups are present. All the functional groups are arranged based on their priority order.
