Which of the following pairs of ions are isoelectronic and isostructural?

Options

  1. AC O 3 2 - , S O 3 2 -
  2. BS O 3 2 - , N O 3 -
  3. CC l O 3 - , S O 3 2 -
  4. DC l O 3 - , C O 3 2 -

Correct answer

C. C l O 3 - , S O 3 2 -

Step-by-step solution

C l O 3 - S O 3 2 - Number of e - 42 42 hybridisation s p 3 s p 3 both are having three bond pair & one lone pair of electrons on central atom hence they are pyramidal in shapes. As both are having 42 electrons and pyramidal shape so, they are isoelectronic and isostructural.
