Which of the following is not true about water molecules?

a. Water molecules are polar
b. Water molecules form hydrogen bonds
c. Water molecules form ionic bonds ***
d. Water is an effective solvent

Correct!

Which of the following is TRUE about water molecules?

Which of the following is TRUE about water molecules?

Which of the following is TRUE about water molecules?

B

c. Water molecules form ionic bonds

Why would water want to form a bond that's so dramatic and charged? It's just too clingy!

To determine which of the following statements is not true about water molecules, let's analyze each option:

a. Water molecules are polar: This statement is true. Water molecules have a bent shape with oxygen being more electronegative than hydrogen, resulting in a partial negative charge on the oxygen atom and partial positive charges on the hydrogen atoms.

b. Water molecules form hydrogen bonds: This statement is true. Due to the polarity of water molecules, they can form hydrogen bonds, which are strong intermolecular forces.

c. Water molecules form ionic bonds: This statement is not true. Water molecules do not typically form ionic bonds. Ionic bonds occur when there is a transfer of electrons between atoms, forming charged ions. Water molecules do not undergo such electron transfers.

d. Water is an effective solvent: This statement is true. Water is known as the "universal solvent" because it can dissolve a wide range of substances. Due to its polar nature, water can surround and dissociate many ionic compounds and polar molecules, allowing them to dissolve.

Therefore, the statement that is not true about water molecules is option c. Water molecules do not form ionic bonds.
