AP Chemistry
3.2 Properties of Solids
3.1 Intermolecular and Interparticle Forces
A student investigates the physical properties of three structural isomers with the molecular formula \(\text{C}_4\text{H}_{10}\text{O}\). The structural formulas and molar masses of the compounds are shown in the table below.
Which of the following correctly ranks the compounds in order of increasing normal boiling point, and provides the best explanation?
| Compound | Structural formula | Molar mass (g/mol) |
|---|---|---|
| X | \(\text{CH}_3\text{CH}_2\text{OCH}_2\text{CH}_3\) | 74.12 |
| Y | \((\text{CH}_3)_3\text{COH}\) | 74.12 |
| Z | \(\text{CH}_3\text{CH}_2\text{CH}_2\text{CH}_2\text{OH}\) | 74.12 |
