Question

Explain hybridization of central atom in :$Si{H}_4$

Answer 1

In the molecule $Si{H}_4$ the central atom Si has 4 valence electrons where the Si atom is forming 4 sigma bonds with H atoms and therefore the stearic number of Si is 4 which imply that the hybridization of the molecule is $s{p}^3$ where the geometry and the shape is tetrahedral.
