Explanation / Answer

22 answer

c.

1-Ethyl-2,4-dimethylcyclohexane

The numbers relegated in every carbon will be most minimal when C1 will be the carbon where methyl(bottom) is joined, in light of the fact that the second branch come nearer to it contrasted with the other one at the top. I think the fundamental need in allotting numbers is the "branches". Give me a chance to quote what McMurry said in regards to this:

"For an alkyl-or corona substituted cycloalkane, pick a state of connection as carbon 1 and number the substituents on the ring so that the second substituent has as low a number as could be expected under the circumstances. In the event that uncertainty still exists, number so that the third or fourth substituent has as low a number as could be expected under the circumstances, until a state of contrast is found."
