Which among the following is not an alkane isomer with 6 carbon atoms?
Correct answer: D. Neopentane
- A. Hexane
- B. 2,3-dimethylbutane
- C. 2,2-dimethylbutane
- D. Neopentane
Explanation
Neopentane is the correct answer because it has 5 carbon atoms, while the other options all have 6 carbon atoms, making them alkane isomers with the specified number of carbon atoms. This distinction makes Neopentane the outlier in this set.
