Which one the following species has plane triangular shape?

Options

  1. AN 3
  2. BN O 3 -
  3. CN O 2
  4. DC O 2

Correct answer

B. N O 3 -

Step-by-step solution

Calculate the electron pair. E . P = Valence   electron   of   central   atom   +   monovalent   atom   +   negative   charge -   positive   charge 2 For NO 3 - E . P = 5 + 1 2 =   3 It means there is the requirement of the three orbitals for the hybridisation. Therefore the hybridisation will be sp 2 s p 2 (triangular planer)
