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 .

Give one example for the following: A non-polar covalent compound to

Hydrogen chloride and water are examples of _________ [polar covalent compounds , non - polar covalent compounds] and a solution of hydrogen chloride in water ______ [ contains , does not contain]free ions.

Ionic bond is defined as the electrostatic force of attraction holding the oppositely charged ions. Ionic compounds are mostly crystalline solid having high melting and boiling points, electrical conductivity in moleten state, solubility in water etc. Covalent bond is defined as the force which binds atoms of same or different elements by mutual sharing of electrons in a covalent bond. Covalent compounds are solids, liquids or gases. They have low melting and boiling points compounds. They are more soluble in non-polar solvents. The valence electrons are involved in formation of covalent bonds is /are called :
