C) Both a and b are true.
D) Neither a nor b is true.

Question

Quizplus · Accepted Answer

Pentane and 2-methylbutane have the same molecular formula, C5H12, but their structures are different, which leads to different physical and chemical properties. They have different boiling points because 2-methylbutane has a branch in its structure, making it more compact and reducing intermolecular forces, leading to a lower boiling point compared to pentane.
