The hybridization of Si in SiO2 is sp3.
Si : [Ne]3s23p2
SiO2 forms a covalent network in which the Si atoms form 4 single bonds to oxygen atoms. The oxygen atoms form 2 single bonds (and have two lone pairs) to Si atoms.
Si is in the same group as C but because it contains the d orbitals (empty but there), Si is two large to form pi bonds.
SiO2 is the same structure and VSEPR as that of CO2.
linear
The molecular geometry of carbon tetra bromide is tetrahedral.
Linear
bent
silicon (IV) oxide or silicon dioxide has giant covalent structure
Square pyramidal
Silicon Tetrafluoride has a tetrahedral molecular geometry. That means there are 4 F atoms around the central atom Si.
makes no sense
