Give reasons for the following:
Ionic compounds do not conduct electricity in solid state.

Ionic compounds are bad conductors of electricity in the solid state.

Why do carbon compounds not conduct electricity ?

How will your demonstrate that the ionic compounds do not conduct electricity in the solid state and can do so in solution.

Give reasons for the following (a) CO_(2) has no dipole moment but SO_(2) and H_(2)O have considerable dipole moments (b) Carbon has two unpaired electrons in the outermost orbit, but it is tetravalent in organic compound (c ) CaF_(2) is more ionic than CaI_(2) (d )Sigma bonds are stronger than pi bonds (e) C_(2)H_(4) is planar while C_(2)H_(2 is linear (f) H_(2)O is more polar than H_(2)S (g) Ionic compounds do not canduct electricity in solid state, but they conduct electricity in solution or in molten state .

Do the covalent compounds conduct electricity ?

(a) Show the formation of magnesium chloride and sodium chloride by transfer of electrons. (b) Identify the ions present in these compounds. (c) Why do ionic compounds not conduct electricity in the solid state?

Explain the following: (a) Sodium chloride is an ionic compound which does not conduct electricity in solid state whereas it does conduct electricity in molten state as well as in aqueous solution. (b) Reactivity of aluminium decrease if it is dipped in nitric acid. (c) Metals like calcium and magnesium are never found in their free state in nature.
