The hybridisation scheme for the central atom includes a d -orbital contribution in
Options
- AI ₃⁻
- BPCl ₃
- CNO ₃⁻
- DH ₂ Se
Correct answer
A. I ₃⁻
Step-by-step solution
I ₃⁻ is linear with central iodine atom undergoing s p^3 d -hybridisation and three lone pairs occupying equatorial position. Thus, this structure include d -orbital contribution to the hybridisation scheme. The structure is, PCl ₃ structure is s p^3 -hybridised with one lone pair. NO ₃⁻ is s p^2 -hybridised and H ₂ Se is s p^3 - hybridised with two lone pairs of Se atom.
