Breaking the hydrogen bond between two water molecules is called dissociation.

true or false

False

False. Breaking the hydrogen bond between two water molecules is called disruption or breaking the bond, not dissociation.

To understand why this is false, let's first look at what dissociation means in chemistry. Dissociation refers to the separation of a molecule into its constituent ions in a solution. In the case of water, dissociation refers to the breaking apart of water molecules into hydrogen ions (H+) and hydroxide ions (OH-) in an aqueous solution.

However, within a water molecule itself, there is a type of intermolecular bond known as a hydrogen bond. A hydrogen bond is a relatively weak attraction between the partially positive hydrogen atom of one water molecule and the partially negative oxygen atom of a neighboring water molecule.

When these hydrogen bonds between water molecules are broken, it is called disruption or breaking the bonds, not dissociation. Disruption of hydrogen bonds can occur due to external factors such as heating, stirring, or adding solutes that interfere with the hydrogen bonding network.

Therefore, the statement that breaking the hydrogen bond between two water molecules is called dissociation is false.
