Hydrogen bonds are moderately strong but they are easily disrupted in the presence of water. ( option B )
- Ionic bonds involve the transfer of electrons from one atom to another to form a bond and hence, are strong bonds.
- Molecular and covalent bonds involve sharing electrons to form bonds and hence cannot be disrupted by water.
- On the other hand, hydrogen bonds are formed between a hydrogen atom and an electronegative atom. These are comparatively weaker than the other bonds mentioned. Water can easily disrupt these bonds.
- Therefore, the hydrogen bond is the correct answer.
