Tetrahedral,$sp^3$

Vedclass · Answer

(D) In $Si(CH_3)_4$ (tetramethylsilane),the central silicon atom is bonded to four methyl groups.Silicon has $4$ valence electrons and forms $4$ sigma bonds with the methyl groups.The steric number is $4 + 0 = 4$,which corresponds to $sp^3$ hybridization.$A$ molecule with $4$ bonding pairs and no lone pairs on the central atom adopts a tetrahedral geometry.
