The polar nature of water molecules gives water many unique properties. Which of these statements is NOT true regarding the properties of water? A) Water is slower to heat than other liquids. B) Water only dissolves other nonpolar molecules. C) Water's surface tension is due to hydrogen bonds between water molecules. D) The hydrogen bonds between water molecules are weaker than covalent bonds.

Respuesta :

B) Water only dissolves other non-polar molecules.

This option is wrong because water is a polar molecule and it can dissolve only other polar molecules.

Answer: Option (B) is the correct answer.

Explanation:

Chemical formula of water is [tex]H_{2}O[/tex] and due to the difference in electronegativity of both hydrogen and oxygen atoms there occurs partial positive charge on the hydrogen atom and partial negative charge on the oxygen atom.

As a result, a molecule of water is polar in nature and generally it can only dissolve polar molecules as like dissolves like.

This means that non-polar molecules will only dissolve in non-polar solvents.

Thus, we can conclude that the statement water only dissolves other non-polar molecules, is NOT true regarding the properties of water.
