Answer:
A solution of Proponic acid is more acidic than ethanol
The Boiling point of propanoic acid is more than ethanol
Explanation:
1.The boiling point of propanoic acid is more than the boiling point of ethanol because of H- bonding.
The electronegative O atom having the lone pair attracts the H of other molecule. Hence the molecules of ethanol show strong intermolecular H-Bonding.
CH3CH2OH-------OHCH2CH3
But in Propanoic acid CH3CH2COOH
This has more extensive H- bonding Because here H-bonding occur from two Oxygen atoms . One is C=O oxygen and other is -OH oxygen.
2.Propanoic acid is more acidic than ethanol because it has acidic Hydrogen . The anion formed after the removal of Hydrogen from Propanoic acid is stabilized by resonance but this does not occur in alcohol. look at the resonance of COO- of carboxylic acids;
