Detailed explanation-1: -A hydrogen bond is an electrostatic attraction between an atom and the positive charge of a hydrogen atom covalently bound to something else. It is weaker than a covalent bond and can be either inter-or intramolecular.

Detailed explanation-2: -Answer and Explanation: A hydrogen bond is not stronger than a covalent bond. Intramolecular bonds such as covalent bonds are always stronger than intermolecular bonds.

Detailed explanation-3: -Covalent bonds require more than 250kj of energy per mole to break whereas a hydrogen bond requires somewhere between 15 and 250 kj per mole to break.

Detailed explanation-4: -Ionic and covalent bonds are both definitely stronger than hydrogen bonds, and usually, ionic bonds are stronger than covalent bonds.

Detailed explanation-5: -The hydrogen bond (5 to 30 kJ/mole) is stronger than a van der Waals interaction, but weaker than covalent or ionic bonds. This type of bond can occur in inorganic molecules such as water and in organic molecules like DNA and proteins.
