Amongst N O 3 - , A s O 3 3 - , C O 3 2 - , C l O 3 - , S O 3 2 - and B O 3 3 - , the non-planar species are

Options

  1. AC O 3 2 - , S O 3 2 - a n d B O 3 2 -
  2. BA s O 3 3 - , C l O 3 - a n d S O 3 2 -
  3. CN O 3 - , C O 3 2 - a n d B O 3 3 -
  4. DS O 3 2 - , N O 3 - a n d B O 3 3 -

Correct answer

B. A s O 3 3 - , C l O 3 - a n d S O 3 2 -

Step-by-step solution

N O 3 - , C O 3 2 - a n d B O 3 3 - have s p 2 hybridisation are hence are planar species while A s O 3 3 - , C l O 3 - and S O 3 2 - have s p 3 hybridisation and hence are non-planar species.
