BITSAT Chemistry Question (2024) — Solution
Options
- A. I _3^ -
- B. PCl _3
- C. NO _3^ -
- D. H _2 Se
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.
