No, hydrogen bonds are not covalent bonds. Hydrogen bonds are a type of intermolecular force that occurs between a hydrogen atom bonded to an electronegative atom (such as nitrogen, oxygen, or fluorine) and another electronegative atom in a different molecule or in a different part of the same molecule.
Hydrogen bonds are formed due to the attraction between the positively charged hydrogen atom and the lone pair of electrons on the electronegative atom. This interaction is weaker than covalent bonds but stronger than other intermolecular forces such as van der Waals forces or dipole-dipole interactions.
Covalent bonds, on the other hand, involve the sharing of electrons between atoms. They are much stronger than hydrogen bonds and hold the atoms within a molecule together.
In summary, hydrogen bonds are a specific type of intermolecular force that occurs between molecules or different parts of the same molecule, and they are not covalent bonds.
