What is the nature of the bonding in anhydrous \(\mathrm{AlCl}_3\) and hydrated \(\mathrm{AlCl}_3\) respectively?
- A Ionic and ionic
- B Ionic and covalent
- C Covalent and ionic
- D Covalent and covalent
Answer & Solution
Correct Answer
(C) Covalent and ionic
Step-by-step Solution
Detailed explanation
Many simple compounds of elements such as \(\mathrm{AlCl}_3, \mathrm{GaCl}_3\) and \(\mathrm{InCl}_3\) are covalent while anhydrous but in aqueous solution, these are ionic in nature. In anhydrous condition, the (charge/radius) ratio, i.e. polarisability of \(\mathrm{Al}^{3+}\)…
