Hydrogen bond v covalent

how are they sim and diff

Both involve chemical bonds where bonds are formed from electrostatic forces

covalent bonds involve the sharing of electrons between atoms. Outer valence shells are filled by the sharing of atoms. This creates a strong bond

Hydrogen bond involves the bonding of Hydrgon to a negatively charged atom. It involves electrostatic forces between atoms.

Rest i don't know.

Help me out please.
