Question

Give reasons for the following observations:

(i) Ionic compounds in general have high melting and boiling points.

(ii) Highly reactive metals cannot be obtained from their oxides by heating

them with carbon.​

Answer 1

ANSWER :

▶️ (i) Ionic compounds have high melting and boiling points due to strong force of attraction between oppositely charged ions.

▶️(ii) It is because these metals themselves are strong reducing agents. Therefore, cannot be reduced by reducing agent like carbon

Answer 2

Explanation:

(a) Due to the high electrostatic force of attraction between the oppositely charged ions, ionic compounds have high melting and boiling points.

(b) Highly reactive metals have high affinity with oxygen. Therefore, their oxides cannot be reduced by carbon.
