OF2↑

(A)

+H2O
The structure of ' A ' (OF2) is as
σ 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 OF2=sp3
Due to repulsion between two lone pairs of electrons, its shape gets distorted. Therefore, the bond angle in the molecule is 103∘.
