What is IUPAC name of the following compound?
Show Hint
Number the ring to give the sum of locants the lowest possible value.
Updated On: May 14, 2026
- 1-Methoxy-3,3-dimethylcyclobutane
- 3-Methoxy-1,1-dimethylcyclobutane
- 3,3-dimethylcyclobutoxymethane
- 1-methoxy-3-isopropyl butane
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Concept
In cyclic ethers, the ring is treated as the parent and substituents are numbered to give the lowest possible locants to the set of substituents.
Step 2: Meaning
Alphabetical order is used to decide the priority of numbering when the locant set is identical from different directions.
Step 3: Analysis
Numbering starts at the carbon with the two methyl groups to give the lowest set of locants (\(1, 1, 3\)) rather than (\(1, 3, 3\)).
Step 4: Conclusion
The methoxy group is at position 3. Alphabetically, "Methoxy" comes before "Methyl". Name: 3-Methoxy-1,1-dimethylcyclobutane. Final Answer: (B)
