Answer

The IUPAC name of the compound is 3-Ethyl-2-methylhexane

Work Step by Step

Look for the longest chain in the compound, number it and name it. Also assign locants/numbers to the substituents to indicate their points of attachment on the main chain. When two different alkyl groups are present, naming is always done in an alphabetical order. In this case, the longest chain has 6 carbon atoms and an ethyl and a methyl group is attached as substituents on carbon numbers 2 and 3 respectively. Hence the name 3-Ethyl-2-methylhexane
