Answer 2

Answer:

22kJ/mol is the energy comparable to the energy contained in a hydrogen bond.

Explanation:

First, let's understand some properties of covalent and hydrogen bonds, and then we will be able to get our answer.

• Covalent bonds are significantly stronger than hydrogen bonds.
• While a typical covalent bond has a strength of 400 kJ mol⁻¹, a hydrogen bond can range in strength from 10 to 40 kJ mol⁻¹.
• As a result, the strength of a hydrogen bond is roughly one hundredth that of a covalent connection.
• A hydrogen bond has a longer bond length than a covalent link.
• For instance, the hydrogen bond between F and H and the covalent bond between H and F in the molecule HF measure 155 pm and 109 pm respectively.

Hence, 22kJ/mol is the energy comparable to the energy contained in a hydrogen bond.
