Question

The structure and hybridization of $N{\left(Si{H}_3\right)}_3$ respectively are:

• A. Pyramidal and $s{p}^2$
• B. Tetrahedral and $s{p}^3$
• C. Planar and $s{p}^2$
• D. Planar and $s{p}^3$

Answer 1

The correct option is C Planar and $s{p}^2$

$N$ atom in $N{\left(Si{H}_3\right)}_3$ donates its lone pair of electron in empty $d$ orbital of $Si$ atom which results into $d\pi -p\pi$ bonding. It has $s{p}^2$ hybridisation and planar structure.
