Answer
The IUPAC name of the compound is 3-Ethyl-2,2,4,5-tetramethylhexane
Work Step by Step
Look for the longest carbon chain and number it. Assign the numbers/locants to the substituents to indicate their position of attachment on the main chain.
In this case, the longest chain has 6 carbon atoms and has 4 methyl groups and one ethyl group as substituents at various positions.
While naming, the substituents are written in alphabetical order hence the name 3-Ethyl-2,2,4,5-tetramethylhexane
