Identify the correct order of boiling points of the following compoundsCH3CH2CH2(1)CH2OH,CH3CH2CH2CHO,(2)CH3CH2CH2COOH(3)

–COOH and -OH group form the hydrogen bond by which they have high boiling point. – COOH group shows strong hydrogen bonding so it forms dimer and have more boiling point than – OH group. While – CHO group does not form hydrogen bond. Thus the reactivity order are as 3 > 1 > 2.
