उत्तर

Propan-1-ol, butan-2-ol, butan-1-ol, pentan-1-ol

Explanation:

Boiling point increases with increase in molecular mass of the alcohols. Among isomeric alcohols 1° alcohols have higher boiling points than 2° alcohols. Thus, correct order is:

Propan-1-ol < butan-2-ol < butan-1-ol < pentan-1-ol.
