Final answer:
Decane has a higher boiling point than acetone due to its larger size and enhanced intermolecular forces.
Step-by-step explanation:
The boiling point of a compound is determined by the strength of intermolecular forces between its molecules. Decane has a higher boiling point than acetone because decane is a larger molecule with more surface area, allowing for stronger London dispersion forces between its molecules.
Acetone, on the other hand, contains a polar C=O double bond which results in dipole-dipole interactions. While dipole-dipole interactions are stronger than London dispersion forces, the larger size and enhanced intermolecular forces of decane result in a higher boiling point.
