What are the bonds between and within water molecules?
Well the intramolecular bond, the bonds within the molecule, are simply covalent
But the intermolecular bonds, the bonds BETWEEN water molecules, are the result of hydrogen bonding.......
And hydrogen bonding occurs when hydrogen is bound to a strongly electronegative element such as oxygen, or nitrogen, or fluorine..
Such hydrogen-bonding interaction is VERY STRONG INTERMOLECULAR FORCE, and elevates the boiling point...
The take-home message is that the normal boiling point of
