Quizplus · Accepted Answer

The molecule has six carbon atoms, all of which are connected to each other in a continuous chain. There are four methyl groups (CH3) attached to the chain, located at positions 2, 3, 3, and 4. Since all four methyl groups are on the same side of the chain, the molecule must have a tetrahedral shape, with the methyl groups pointing away from the chain. Therefore, the correct name is 2,3,3,4-tetramethylhexane (choice C).
