According to IUPAC numbering rules for alicyclic rings, what is the correct name for a cyclohexane r — IUPAC and Nomenclature Chemistry Question

💡 Solution & Explanation

When two substituents are at structurally equivalent positions, the numbering is done such that the substituent coming first in alphabetical order gets the lower number. "Ethyl" precedes "methyl", so it is numbered starting at the ethyl group, making it 1-ethyl-2-methylcyclohexane.
