Answer :
The substances in the increasing order of boiling point are
CH3CH2CH3<CH3OCH3<CH3CHO<CH3CH2OH
What is the boiling point of a compound?
The boiling point of organic compounds can reveal vital details about their structural makeup and physical features. The boiling point of a substance aids in identifying and describing it. When the air pressure and the vapour pressure of a liquid are equal, the liquid boils. The kinetic energy of a molecule affects vapour pressure.
Despite having similar molecular weights across the board, CH3CH2OH exhibits the most intermolecular h-bonding, giving it the greatest boiling point.
Lowest boiling point for CH3CH2CH3 due to weak van der Waals forces. Furthermore, CH3CHO has a higher boiling point than CH3OCH3 because it exhibits more interactions between dipoles.
Therefore the order of increasing boiling point goes CH3CH2CH3<CH3OCH3<CH3CHO<CH3CH2OH
