Which of the compounds shown above is correctly identified by the name 3,3-dimethylpropane?

Question

Quizplus · Accepted Answer

3,3-Dimethylpropane cannot exist because propane, a three-carbon chain, cannot have two methyl groups attached to the third carbon (as numbering starts from one end). The correct structure for a compound named with "3,3-dimethyl" would require at least a five-carbon backbone to provide positions 3 and 3 for substitution, making the name 3,3-dimethylpropane chemically impossible.
