$N(SiH_3)_3$

Vedclass · Answer

(C) In $N(SiH_3)_3$,the nitrogen atom has a lone pair of electrons. Silicon has vacant $3d$ orbitals. The lone pair on the nitrogen atom is donated into the vacant $3d$ orbital of silicon,forming a $p\pi-d\pi$ back bond. This back bonding changes the hybridization of nitrogen from $sp^3$ to $sp^2$,making the molecule planar (trigonal planar). While $BF_3$ is also planar,it is planar due to its $sp^2$ hybridization and the nature of its bonding,but $N(SiH_3)_3$ is a classic example of a molecule that becomes planar specifically due to back bonding where it would otherwise be pyramidal like $N(CH_3)_3$.

Which of the following is planar due to back bonding?
