<span>Hydrogen bonds do not
form in all molecules because hydrogen can only form these bonds with highly
electronegative atoms. It is a weak type of force that happens when a hydrogen
atom is bonded to an atom which has a high electronegativity. For water, it is present because hydrogen is bonded to oxygen which is very electronegative.</span>
True, everything is made up of matter
