In

\left[{Al}\left({H}_2{O}\right)_6\right]^{3+}

ion, the hybridisation state of

{Al}

and the shape of the ion respectively are

View answer and explanation

Correct option: C

{sp}^3{d}^2

, octahedral

Option C (

{sp}^3{d}^2

, octahedral) is correct because the aluminum ion is surrounded by six water ligands, resulting in

sp^3d^2

hybridization and an octahedral geometry.
