Aldehydes boil higher than hydrocarbons of like mass because of:
AIonic attraction
BMetallic bonding
CDipole interactions
DHydrogen bonding
Answer & Solution
Correct answer: C. Dipole interactions
1. The carbonyl group makes these molecules polar.
2. Polar molecules associate weakly with one another.
3. Those dipole to dipole interactions raise the boiling point.
