Chemistry - CHEMICAL BONDING Question with Solution | TestHub
When a hydrogen atom is bonded to a highly electronegative atom (like F, O or N) comes under the influence of another strongly electronegative atom, then a weak electrostatic force of attraction is developed between them, which is called as hydrogen bond.
In which of the following condense phase is formed by intermolecular H-bond :-
Options:(select one or more)
Answer:
Solution:
Intermolecular hydrogen bonding leads to association between molecules, forming condensed phases like liquids or solids. Sulphuric acid and Ortho-phosphoric acid contain multiple –OH groups, enabling strong intermolecular H-bonding. Para-hydroxy benzoic acid also forms intermolecular H-bonded structures due to –OH and –COOH groups. n-Butane lacks electronegative atoms, so it cannot form H-bonds. Hence, correct answer is (A, B, C).
