Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

Covalent bonds do not dissolve in water, but some covalent compounds do. Covalent molecules are attracted to each other by various intermolecular forces such as H-bonds, dipole-dipole forces, and London dispersion forces. Water molecules are attracted to each other by strong H-bonds. A polar solute may be attracted to the water molecules as strongly as the water molecules are attracted to each other. It should contain a highly electronegative atom such as N or O or, even better, an N-H or an O-H bond, because they can form H-bonds to the water molecules. It will then be able to work its way among the water molecules (dissolve). Sugar and ethanol are covalent compounds that are soluble in water, because they contain O-H groups that can H-bond to the water.
