Why Is SiO2 Tetrahedral? - Ceramics

Why is SiO2 not linear? Because Si doesn’t form double bond with oxygen atom due to it’s large size. Hence SiO2 is not linear. Electronegativity of carbon, silicon and oxygen atoms are 2.5, 1.7 and 3.5 respectively. The electronegativity difference between carbon and oxygen atom is 1, that satisfy to form polar covalent bond in CO2.
