In which one of the following pairs the two species have identical shape, but differ in hybridisation?

Options

  1. Al ₃⁻, BeCl ₂
  2. BNH₃, BF₃
  3. CXeF₂, I₃⁻
  4. DNH₄⁻, SF₄

Correct answer

A. l ₃⁻, BeCl ₂

Step-by-step solution

Central I in I ₃⁻ undergoes s p^3 d hybridisation giving a linear shape with three lone pairs at equatorial positions. Beryllium chloride has linear structure with s p hybridisation of Be atom.
