Click on the carbon atom that should be designated as #1 when
naming this compound systematically.
Answer
General guidance
The rules for naming the compound are as follows:
1. Find and name the longest continuous carbon chain.
2. Identify and name groups attached to this chain.
3. Number the chain consecutively, starting at the end nearest a substituent group.
4. Designate the location of each substituent group by an appropriate number and name.
5. Assemble the name, listing groups in alphabetical order using the full name (e.g. cyclopropyl before isobutyl).
6. The prefixes di, tri, tetra etc., used to designate several groups of the same kind, are not considered when alphabetizing.
Step-by-step
Step 1 of 2
The structure is as follows:
In this structure, there are five carbon atoms in the cyclic ring. So, the parent name of this structure is cyclopentane. Number the chain and see that the substituents get the lowest possible number.
Step 2 of 2
The structure contains three substituents, in which two are methyl and one is ethyl.
Thus, the systematic name of the compound is 1-ethyl-2,4-dimethylcyclopentane.
The ethyl group is at 1st carbon atom and the methyl groups are at 2nd and 4th carbon atoms. So, the name of the compound is 1-ethyl-2,4-dimethylcyclopentane.
Answer
Thus, the systematic name of the compound is 1-ethyl-2,4-dimethylcyclopentane.
Answer only
Thus, the systematic name of the compound is 1-ethyl-2,4-dimethylcyclopentane.
