Aren't hydrogen bonds composed of covalent bonds?
I know that there is a hydrogen bond between H2O and NH3. But aren't H2O and NH3 still polar covalent bonds?

A hydrogen bond is a weak attraction BETWEEN 2 molecules of certain make-up.
It is really a weak positive charge attracted to a weak negative charge.
But of course, the molecules in question
are composed of atoms held together by covalent bonds.
The H2O and NH3 that you mention CONTAIN covalent bonds
However, the attraction between those molecules is NOT a covalent bond.
If it were, then they would no longer be separate molecules.
It's sort of like 2 magnets: a hydrogen bond would be represented by
the attraction between the 2 magnets.
And that attraction is not the same thing
that is holding the atoms of the magnet together.

Covalent bonds hold the two hydrogen and one oxygen together in 'one' molecule.
Hydrogen bonds are present 'between' H2O 'molecules'
One water molecule being attracted to another.
Its a different thing i believe.
Hydrogen bonds have a covalent character though.
