Question
The compound with the lowest boiling point is
Correct Answer
Option D is the correct answer.
Detailed Explanation
Propane (CH3CH2CH3) has the lowest boiling point because it cannot form hydrogen bonds and has the weakest intermolecular forces (only van der Waals). Water and ethanol have hydrogen bonding, and dimethyl ether has dipole-dipole forces.
