The incorrect statement regarding `O(SiH_(3))_(2) and OCl_(2)` molecule is/are

Options

A. The strength of back bonding is more in `O(SiH_(3))_(2)` molecule than `Ocl_(2)` molecule
B. `Si-O-Si` bond angle in `O(SiH_(3))_(2)` is greater than `Cl-O-Cl` bond angle in `OCl_(2)`
C. The nature of back in both molecules is `2p_(x)-3d_(pi)`
D. Hybridisation of central O-atom in both molecules is same

Answer

D

Explanation

hybridisation of O-atom : `sp^(2)` due to more extent of `(2p_(pi)-3d_(pi))` back bonding.
Hybridisation of O-atom remains `sp^(3)`, becouse of less effective `(2p_(pi)-3d_(pi))` back bonding due to d-orbital resonance
