Answer 2

Name of this alkane is 1-ethyl-3-methylcyclohexane

Step-by-step explanation:

It is a derivative of cyclohexane. So main carbon chain is cyclohexane.

There are two substituents- methyl and ethyl

Numbering starts by assigning carbon attached with ethyl group as 1 and carbon attached to methyl group is numbered as 3 to give lowest possible numbering.

Carbon bearing ethyl group is numbered as 1 because "e" comes first compared to "m" in alphabetical order
