Correct Answer - ABD
(A)Steric repulsions of bulkier groups and `ppi-dpi` dative bonding favour for a linear Si-O-Si group.
(B)Due to stabilization of the conjugate base anion by O `(ppi)to Si(dpi)`bonding motion.
( C)In is pyramidal because `ppi-dpi` bonding is not effective due to the bigger size of phosphorus atom
(D)Most effective due to small size of chlorine.
