When BCl₃ is treated with water, it hydrolyses and forms [B(OH)₄]⁻ only, whereas AlCl₃ in acidified aqueous solution forms [Al(H₂O)₆]³⁺ ion. Explain what is the hybridisation of boron and aluminium in these species?

Options

  1. ABoron - sp 3 hybridization, Aluminium - sp³d 2 hybridization
  2. BBoron - sp² hybridization, Aluminium - sp² hybridization
  3. CBoron - sp³ hybridization, Aluminium - sp² hybridization
  4. DBoron - sp³ hybridization, Aluminium - sp³ hybridization

Correct answer

A. Boron - sp 3 hybridization, Aluminium - sp³d 2 hybridization

Step-by-step solution

Correct Option is : (A) Boron - sp 3 hybridization, Aluminium - sp³d 2 hybridization
