Question

Which of the following describes the types of bonds broken in the solute and formed with water when hydrogen fluoride dissolves?

a. Covalent bonds
b. Ionic bonds
c. Hydrogen bonds
d. Metallic bonds

Answer 1

When hydrogen fluoride (HF) dissolves in water, hydrogen bonds are formed between the hydrogen atom in HF and the oxygen atoms in water molecules.

Step-by-step explanation:

When hydrogen fluoride (HF) dissolves in water, hydrogen bonds are formed between the hydrogen atom in HF and the oxygen atoms in water molecules. These hydrogen bonds weaken the covalent bond between the hydrogen and fluorine in HF, causing it to stretch and ultimately break. As a result, the hydrogen in HF becomes fully bonded to oxygen, forming the hydronium ion (H3O+), and the fluorine becomes a fluoride ion (F-). Therefore, the correct answer is c. Hydrogen bonds.
