Vedclass · Answer

(B) The compound $(SiH_3)_3N$ is planar and less basic than $(CH_3)_3N$. In $(SiH_3)_3N$,the lone pair of electrons on the $N$ atom is donated into the vacant $d$-orbitals of the $Si$ atoms,resulting in $p\pi - d\pi$ back bonding. This delocalization of the lone pair makes the molecule planar and significantly reduces its availability for protonation,making it less basic than $(CH_3)_3N$. In $(CH_3)_3N$,carbon lacks vacant $d$-orbitals,so no such back bonding occurs,and the lone pair remains localized on the $N$ atom.
