Question

Give the IUPAC names of the following ethers:
Given ether:

Answer 1

Hint: First determine the parent chain containing a maximum number of carbon atoms. Cycloalkanes are cyclic compounds where no double bonding or triple bonding is present. In IUPAC naming the term is used as a suffix.

Complete step by step solution:
Ether functional groups consisting of chemical compounds are determined by the general formula $R - O - R'$ , where R is the alkyl group.
International Union of Pure and Applied Chemistry are the sets of rules that are applied to determine the chemical name of the compound. This is known as the IUPAC naming system.
The given chemical compound is shown below.

Numbering of Carbon atom

• 1. Determination of Root Word: In the given compound, the maximum number of carbon atoms present in a continuous chain is 6, so the hydrocarbon is hexane and the root word is “Hex”. As it is a cyclic compound then the hydrocarbon will be referred to as cyclohexane.

2. Determination of names and position of locants: In the given compound, one “Ethoxy” group is attached to the 4th position and two “Methyl” groups are attached to the first position.

3. Determination of suffix: As there is no availability of double or triple bonds, it is considered a saturated hydrocarbon. The suffix used will be “ane”.

The IUPAC name will be 4-ethoxy-1,1-dimethylcyclohexane.
Hence, the answer is “4-ethoxy-1,1-dimethylcyclohexane”.

Note: The group with less number of carbon atoms attached to the oxygen is treated as a substituent group whereas the group comprising more number of carbon atoms is considered as the parent group. Always the substituent group is written prior to the parent group. As the ethyl group is attached to the oxygen atom, therefore the substituent group is termed “Ethoxy”.
