Question

Quizplus · Accepted Answer

Heptane and 2,2,3-trimethylbutane have different structures and therefore have different physical properties. Specifically, their melting and boiling points will be different. Therefore, neither option A nor B is correct, and option C (which suggests that they have both the same melting and boiling point) is also incorrect. The accurate answer is D (none of these).
