Which of the following provides explanation for the ionic nature of `AlCl_3. 6H_2O` although we know that `AlCl_3` is covalent?A. ResonanceB. Concept of hydration energyC. Concept of molecular orbitalsD. ionisation energy |
|
Answer» Correct Answer - B Ionic nature of `AlCl_3. 6 H_2O` is explained on the basis of hydration energy released when `Al^(3+)` surrounded by `6H_2O` molecules. This energy compensates the high ionisation energy required for the formation of `Al^(3+)` from Al. |
