Water boils at a higher temperature than a non-polar solvent like ether

a. a large amount of energy is released when water dissociates into oppositely charged ions.

b. a large amount of energy is required to break the polar covalent bonds that hold each water molecule together.

c. a large amount of energy is required to remove electrons from the hydrogen atoms in each water molecule.

d. a large amount of energy is required to remove electrons from the oxygen atom in each water molecule.

e a large amount of energy is required to break the many hydrogen bonds that restrict the movement of individual water molecules.
