316214 Assertion :
Anhydrous \(\mathrm{AlCl}_{3}\) is covalent but hydrated \(\mathrm{AlCl}_{3}\) is ionic.
Reason :
In water, \(\mathrm{Al}_{2} \mathrm{Cl}_{6}\) dissociates into hydrated \(\mathrm{Al}^{3+}\) and \(\mathrm{Cl}^{-}\)ions due to high heat of hydration of these ions.

316215 Which one of the following elements is unable to form \({\text{MF}}_{\text{6}}^{{\text{3 - }}}\) ion?

316233 Assertion :
Although \(\mathrm{PF}_{5}, \mathrm{PCl}_{5}\) and \(\mathrm{PBr}_{5}\) are known, the pentahalides of nitrogen have not been observed.
Reason :
Phosphorus has lower electronegativity than nitrogen

316216 The Lewis acid character of boron trihalides follows the order
