no bonds are broken the compound is changing phase not breaking bonds
Ionic bonds readily disassociate in aqueous solutions. Table salt, or sodium chloride with the molecular formula of NaCl breaks up into Na+ and Cl- ions in these solutions.
the bonds between the water molecules are broken
Chemical bonds are both formed and broken during chemical reactions. For example, bonds are formed and broken in the synthesis reaction 2H2 + O2 = 2H2O. The bonds in both diatomic oxygen and hydrogen are broken, forming new bonds to form a water molecule.
All four C-H bonds in methane are broken during combustion.
Hydrogen bonds are easily broken. Think of swimming through water.
Heat. Intermolecular Hydrogen bonds (between two water molecules) are broken as water is heated to boil.The intramolecular hydrogen bonds (between H and O) stay intact

The primary bond that is broken when water is boiled is hydrogen bonds. There are other weaker intermolecular forces at work as well, but these are much weaker and not as significant. Once the hydrogen bonds are broken, the water molecules are not held as tightly together and can escape the liquid as gas.

"Individual hydrogen bonds are weak and easily broken; however, they occur in very large numbers in water and in organic polymers, creating a major force in combination. Hydrogen bonds are also responsible for zipping together the DNA double helix." -lumenlearning
