D) Neither a nor b is true.

Question

Quizplus · Accepted Answer

Heptane and 2,2,3-trimethylbutane have different structures and therefore have different physical properties. Heptane has a higher molecular weight and longer carbon chain, resulting in a higher boiling point than 2,2,3-trimethylbutane. Additionally, they likely have different melting points due to their differing structures.
