Please mention the method of numbering carbon atoms when mentioning the answer
IUPAC nomenclature of cyclic compounds.
Ring is parent chain due to larger number of carbon atoms.
Numbering should be so as to assign the lowest possible number to the locants.
We have three cases. Select the lowest number.
1.2.4 ✔
1.2.6 ❌
1.3.4 ❌
For mentioning locants, use alphabetical order.
Hopw this helps.
Thank you
