Aluminium chloride in acidified aqueous solution forms an ion having geometry

Options

  1. AOctahedral
  2. BSquare Planar
  3. CTetrahedral
  4. DTrigonal bipyramidal

Correct answer

A. Octahedral

Step-by-step solution

Aluminium Chloride in acidified aqueous solution forms octahedral Al ( H 2 O ) 6 3 + ion. AlCl 3 → Acidified aqueous solution Al H 2 O 6 3 + In this complex the 3 d orbital of Al are involved and the hybridisation state of Al is sp 3 d 2 . Hence, the answer is option A.
