On moving down the group, acidic nature of oxides of group 14

Question

On moving down the group, acidic nature of oxides of group 14 (A) Decreases (B) Increases (C) Remains same (D) Increases then decreases

Tardigrade Admin · Accepted Answer

The acidic nature decreases with increase of atomic number of the oxides. CO 2 and SiO 2 are acidic and GeO 2, SnO 2 PbO 2 are amphoteric. Basic character of both mono and dioxide increases down the group.
