Paragraph: The coordination number of Ni ²⁺ is 4 . NiCl ₂+ KCN (excess) A (cyano complex) NiCl ₂+ conc. HCl (excess) B (chloro complex) Question: The hybridization of A and B are

Options

  1. Ad s p^2, s p^3
  2. Bs p^3, s p^3
  3. Cd s p^2, d s p^2
  4. Ds p^3 d^2, d^2 s p^3

Correct answer

A. d s p^2, s p^3

Step-by-step solution

Hybridisation of Ni in K ₂ [ Ni ( CN )₄ ] is d s p^2 and in K ₂ [ Ni ^2 ( Cl ₄ ) ] is s p^3 (Detail see in question no. 25).
