1) why do alcohol have higher b.pt than halialkanes of similar molecular masses​

Answer 1

Answer:

The reason why alcohols have a higher boiling point than alkanes is because the intermolecular forces of alcohols are hydrogen bonds, unlike alkanes with van der Waals forces as their intermolecular forces. The image below shows ethanol molecules with a hydrogen bond.
