Answers (1)

The answer is the option (iii). To name the compounds containing carbon as their substituent group, steeps of nomenclature involved are –

1.         Identify the longest carbon chain, also known as the parent chain. Calculate the number of carbons present and assign its root name.

2.         Numbering of the parent chain by assigning the smallest number to the first substituent.

3.         Recognise the position and name of all substituent carbon groups.

4.         In the presence of identical groups, use the group prefix such as di, tri, tetra, etc.

5.         Alphabetically arrange the substituent position and names in front of the root name. While making the order, prefix like di, tri, tetra should not be accounted for except iso and cyclo.

By following these rules, the IUPAC name of the given compound is \text {2-methoxypropane}. So the correct option is (iii) \text {2-methoxypropane}
