Dear Student
IUPAC rules for nomenclature
- Find and name the longest continuous carbon chain.
- Identify and name groups attached to this chain.
- Number the chain consecutively, starting at the end nearest a substituent group.
- Designate the location of each substituent group by an appropriate number and name.
- Assemble the name, listing groups in alphabetical order.
The prefixes di, tri, tetra etc., used to designate several groups of the same kind, are not considered when alphabetizing.
For naming this compound, first we will check the length of continous carbon chain, which is 4 membered in this case. So, the parent is saturated 4 membered alkane,i.e butane.
Since there are two groups attache to the chain, chloro and nitro. According to alphabetical order we will name chloro first then nitro.
So the name is-----
2-chloro-4-nitrobutane
We hope that clarifies your query.
