The correct IUPAC name of the compound given below is : CH ₃- CH ( CH ₃)-( CH ₂)₄- CH ( CH ₃)- CH ( C ₂ H ₅)- CH ₃

Step-by-step solution

First, identify the longest continuous carbon chain. The straight horizontal chain contains 9 carbon atoms. However, if we include the ethyl group ( - C ₂ H ₅ ) as part of the main chain, we get a continuous chain of 10 carbon atoms (decane). The substituents on this decane chain are three methyl groups. Next, we number the chain to give the lowest locants to the substituents: Numbering from left to right (starting from the left CH ₃ ): the methyl groups are at positions 2, 7, and 8. The locant set is (2, 7, 8). Nu
