The correct statement about I Cl 5 and I Cl 4 - is:

Options

  1. AI Cl 5 is trigonal bipyramidal and I Cl 4 - is tetrahedral.
  2. BBoth are isostructural.
  3. CI Cl 5 is square pyramidal and I Cl 4 - is tetrahedral.
  4. DI Cl 5 is square pyramidal and I Cl 4 - is square planar.

Correct answer

D. I Cl 5 is square pyramidal and I Cl 4 - is square planar.

Step-by-step solution

I C l 4 - = l p + b p = 2 + 4 = s p 3 d 2 Square planar I C l 5   = 1   l p + 5   b p = 6 = s p 3 d 2 Square pyramidal.
