In which of the following molecules/ions, the central atom is s p 2 hybridized?

Options

  1. ANH 2 − , & H 2 O
  2. BNO 2 − & H 2 O
  3. CBF 3 & NO 2 −
  4. DNO 2 − , NH 2 −

Correct answer

C. BF 3 & NO 2 −

Step-by-step solution

The combination of one s and two p - orbitals to form three hybrid orbitals of equal energy is known as sp 2 hybridization These sp 2 hybridized orbitals are oriented at an angle of 120 ° So the structure of BF 3 molecule is But in case on NO 2 - nitrogen molecule contains a single lone pair and double bond So it is also sp 2 hybridised
