The type of hybridisation of P atom in PCl ₅ , PCl ₄⁺ and PCl ₆⁻ is (respectively)

Options

  1. As p^3, s p^3 d s p^3 d^2
  2. Bs p^3 d, s p^3, s p^2 d^2
  3. Cs p^ 3, s p^3 d^2, s p^3
  4. Ds p^3 d^2, s p^3, s p^3 d

Correct answer

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

Step-by-step solution

In PCl ₅ No. of e⁻ pairs around central atom P =5 No of lone pairs =0 and hybridisation-sp ^3 d Shape = trigonal bipyramidal. In PCl ₄⁺- number. of e⁻ pairs =4 , lone pairs =0 , hybridisation =s p^3 and shape tetrahedral In PCl ₆⁻- number of e⁻ pairs =6 , lone pairs =0 , hybridisation =s p^3 d^2 and shape is octahedral
