Assertion : Water is a good solvent for ionic compounds but poor one for covalent compounds. Reason :Hydrogen energy of ions realeases sufficient energy to overcome lattice energy and break hydrogen bonds in water, white covalent bonded compound interact so weakly that even van der walls force between molecule of convalent compounds cannot be broken .
