Question

What is the IUPAC name of the compound \[{C_6}{H_5}O{(C{H_2})_6}C{H_3}\] ?

Answer 1

Hint: While naming a chemical compound, we should first check the type of compound as the IUPAC guidelines for nomenclature are different for different types of compounds. Since here we are dealing with a carbon compound, we will use the guidelines specified for carbon compounds.

Complete answer:
First, let’s check the IUPAC guidelines for the nomenclature of carbon compounds. These are,
Longest chain rule: The parent chain of a given compound is considered the longest chain. The chain can be in the form of a straight-chain or a chain of any other shape. It is indicated by root words.
Lowest set of locants: The carbon atoms that belong to the parent chain is numbered using natural numbers.
Multiple instances of the same substituent: Prefixes that indicate the total number of the same substituent group in the given compound is mentioned, such as di, tri, etc.
Naming of different substituents: In the organic compounds that contain multiple substituents, the corresponding substituents are arranged in alphabetical order of names.
The naming of different substituents present at the same positions: When two different substituent groups are present at the same position of the compound, the substituents are named in ascending alphabetical order.
The IUPAC format for naming of compounds is Locant \[ + \] Prefix \[ + \] Root \[ + \] Locant \[ + \] Suffix
Here the root word indicates the total number of carbon atoms present in the parent chain. The root words are meth, eth, prop, but etc.
Now, let’s name the compound using the above scheme.
Here the parent chain contains seven carbon atoms, hence the root word will be hept. Since there are only single bonds in the compound, we will add -ane at the end of the root word and it becomes heptane. The substituent group present here is a phenoxy group (phenyl \[ + \] oxygen is called phenoxy when used as a prefix). The number of locants here is \[1\] as there is only one substituent group.
Hence the name of \[{C_6}{H_5}O{(C{H_2})_6}C{H_3}\] is \[1 - \]phenoxyheptane.

Note:
The common name of \[{C_6}{H_5}O{(C{H_2})_6}C{H_3}\] is heptyl phenyl ether. Sometimes, the given name of a compound might be the common name and you will be asked to write the IUPAC name. The best thing to do at that time is to first write the molecular formula and then write the IUPAC name as it will decrease your chances of making any kind of mistake.
