WebAs we move down in a group, acidic nature of oxides decreases and basic nature increases. Si,Ge,Sn and Pb belongs to group 14, among them Si is the first element and Pb is last, hence, oxides of Si are acidic and oxides of Pb are basic while Ge and Sn are amphoteric as they came in middle of group. So, the correct order is option D. WebSiO₂ is high (beta) Cristobalite structured and crystallizes in the tetragonal I̅42d space group.
