Quizplus · Accepted Answer

The longest continuous carbon chain is 7 carbons long, so the root name is heptane. There are two substituents on carbon 5 and one on carbon 2, so the name is 5,5-diethyl-2-methylheptane. Option A has two substituents on carbon 3 instead of 5, and option D has three substituents on a single carbon. Option B is not a valid IUPAC name.
