Select the correct statement(s) with respect to the `p pi-dpi` dative bond.

A

In `(Ph_3Si)_2O`, the Si-O-Si group is nearly linear

B

Silanols such as `(CH_3)_3` SiOH are stronger protonic acids then their carbon analogs

C

Trisilysl phosphine `(H_3Si)_3` P is planar

D

`CIO_4^-` does not polymerise at all

Text Solution

Verified by Experts

The correct Answer is:
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.
