The structural formulas and normal boiling points of two isomers with the molecular formula \(\text{C}_5\text{H}_{12}\) are shown in the table below.
Which of the following statements best explains why pentane has a higher normal boiling point than \(2,2\)-dimethylpropane?
| Compound | Structural formula | Normal boiling point (\(^\circ\text{C}\)) |
|---|---|---|
| Pentane | \(\text{CH}_3\text{CH}_2\text{CH}_2\text{CH}_2\text{CH}_3\) | \(36.1\) |
| \(2,2\)-dimethylpropane | \(\text{C(CH}_3)_4\) | \(9.5\) |
