Fluorine reacts with dilute NaOH and forms a gaseous product A . The bond angle in the molecule of A is

Options

  1. A104^ 40^
  2. B103^
  3. C107^
  4. D109^ 28^

Correct answer

B. 103^

Step-by-step solution

The structure of ' A ' ( OF ₂ ) is as bonds made by O =2 Lone pairs of electrons on O =2 No. of orbitals used by O for hybridisation =2+2=4 Hybridisation of O in OF ₂=s p^3 Due to repulsion between two lone pairs of electrons, its shape gets distorted. Therefore, the bond angle in the molecule is 103^ .
