What can easily break a hydrogen bond?

Oil
Water or heat
Acids
Alkalis

The correct answer is: Water or heat

Hydrogen bonds are weaker than covalent bonds and can be easily broken by the presence of other substances such as water or heat. Oil, acids, and alkalis do not have the same effect on hydrogen bonds and therefore are not correct options. Water and heat can disrupt the electrostatic attraction between hydrogen and another atom, breaking the hydrogen bond. This allows the hydrogen atom to bond with a different atom, altering the overall structure and properties of the substance. Therefore, option B is the most accurate answer.
