MCQ
Anhydrous $ALCl_3$ is covalent however,when it is dissolved in water hydrared ionic species are formed. This transformation is owing to
  • A
    the trivalent state of $Al$
  • ✓
    the large hydration energy of $Al^{3+}$
  • C
    the low hydration energy of $Al^{3+}$
  • D
    the polar nature of water
✓

Answer

Correct option: B.
the large hydration energy of $Al^{3+}$
b
When $AlCl _3$ dissolves in water, it dissociates into cation and anion. And due to hydration of these ions compound; it dissolves in water so this happens due to large hydration energy of ions.
