Which of the following properties is NOT significantly affected by hydrogen bonding?
- Boiling point of H3PO4
- Viscosity of H2O2
- Basicity of maleic acid
- Acidic strength of o-hydroxybenzoic acid
Correct answer: Basicity of maleic acid
Solution
H3PO4 has an abnormally high boiling point due to intermolecular H-bonding. H2O2 has high viscosity due to strong H-bonding network. Salicylic acid (o-hydroxybenzoic acid) has enhanced acidity due to intramolecular H-bonding stabilizing the carboxylate. Maleic acid's basicity (proton acceptance) is not meaningfully linked to hydrogen bonding — this is an intrinsic electronic property.
