Step-by-step explanation:
The compound in question is named 5-ethyl-3-methyloctane according to the IUPAC system.
In organic chemistry, substituents are atoms or groups of atoms that are attached to the parent chain of a molecule. In this case, the substituents are 5-ethyl- and 3-methyl-. The substituents are named by placing the number from the parent carbon chain in front of the name of the substituent. The larger alkyl group, 5-ethyl-, is listed first because it comes before the smaller alkyl group, 3-methyl-, alphabetically.
