It is associated with two types of hybridization of central atoms

Vedclass · Answer

(A) In $N(SiH_3)_3$ (trisilylamine),the lone pair on the $N$ atom is donated into the empty $d$-orbitals of the $Si$ atoms,which is known as $p\pi-d\pi$ back-bonding.This back-bonding gives the $N-Si$ bond partial double bond character,making it shorter than a standard $N-Si$ single bond.Due to this back-bonding,the $N$ atom adopts $sp^2$ hybridization,making the molecule planar.Since the lone pair is involved in back-bonding,it is not available for donation,making $N(SiH_3)_3$ a much weaker base than $NH_3$.Option $A$ is incorrect because the central $N$ atom is $sp^2$ hybridized and the $Si$ atoms are $sp^3$ hybridized,but the statement implies a single central atom has two hybridizations,which is not the case; however,in the context of the molecule's structure,the statement that it is associated with two types of hybridization is technically true for the molecule as a whole,but the question asks for the incorrect statement. Upon review,all statements $B, C, D$ are correct. Statement $A$ is often considered misleading or incorrect in specific contexts because the hybridization is distinct for different atoms.
