Solution
The correct option is D Statement 1 is False, statement 2 is True
Si−Si: 340 kJ/mole
Si−O: 452 kJ/mole
Thus, Si−O bond is stronger, owing to the higher overlap due to the small size of oxygen atom.
The Si=Si double bonds are very unstable due to the instability of the p-p sideways overlap as the p orbitals which need to overlap sideways are very far from each other due to the large size of the Si atom.
