Water does not dissociate a covalent bond that is non polar.


In forming a solution with an ionic compound the water does dissociate the ionic bond holding the compound together and separating the compound into component parts and ions.

In forming a solution with covalent compounds the water breaks the inter molecular attractions that hold the molecules of compound together. This forms a solution with the inter molecular bonds of the covalent molecule intact.

For example in sugar water, the molecules of sugar are separated from each other " floating" in solution. The covalent bonds within each individual sugar molecule are not broken.

Water does not dissociate the covalent bonds of a non polar molecule.
