Covalent bonds differ from hydrogen bonds in the following ways:
1. Covalent bonds can involve any atoms, while hydrogen bonds specifically involve hydrogen atoms.
2. Covalent bonds require the sharing of electrons between atoms, whereas hydrogen bonds are electrostatic attractions between a hydrogen atom and an electronegative atom.
3. Covalent bonds are generally stronger than hydrogen bonds.
4. Covalent bonds can result in the formation of molecules that may or may not have polar charges, depending on the electronegativity difference between the atoms involved. Hydrogen bonds always result in the formation of molecules with polar charges.
