Question by JJ: How do the hydrogen bonds between water molecules compare to the covalent bonds within water molecules?
How do the hydrogen bonds between water molecules compare to the covalent bonds within water molecules?
Hydrogen bonds are between two hydrogen atoms. Covalent bonds are between a hydrogen and an oxygen.
The hydrogen bonds are more easily broken than the covalent bonds.
The hydrogen and covalent bonds are both polar.
The hydrogen and covalent bonds both involve electron sharing.

Hydrogen are more easily broken. About ten times more easily.
Both types of bonds are polar.
Hydrogen bonds do not involve electron sharing, unlike the covalent bonds.
Hydrogen bonds are between one hydrogen atom which is delta + with a oxygen’s lone pair on another water molecule which is delta – Don’t get too confused here, I’m basically saying one is more electronegative than the other. Covalent bonds share electrons between the H2 and O2 atoms thus are much stronger than hydrogen bonds, which are much weaker intermolecularar forces.
When you heat water you are actually breaking the H-bonds BETWEEN the molcules, it is extremly difficult to break the stronger covalent bonds within the atoms however.
