Solution:Concept- Chemical compounds are generally of two types: covalent compounds and ionic compounds. Ions with the opposite charge form ionic compounds, usually as a result of the reaction of a metal with a nonmetal. In covalent compounds, the elements form the compound by sharing electrons, resulting in an electrically neutral molecule.
In solution, when dissolves in water, dissociation occurs and dissociates into and . Now, Hydration of and ions occur due to the large hydration energy of ions as it dissolves in water.
Anhydrous is covalent, but when dissolved in water, hydrated ionic species are formed. This transformation is due to the large hydration energy of .
Thus, in liquid or gas phase exists as a covalent compound, or as in the form of dimers.
But, when we dissolve in water, it liberates the ions of aluminium ( )and chloride ion ().
Hence, the correct answer is 2.
