The basicity of the dioxide alters in the order

Question

Consider the following dioxide of group 14 1 . C O 2 2 . S i O 2 3 . G e O 2 4 . S n O 2 5 . P b O 2 The basicity of the dioxide alters in the order

TestHub · Accepted Answer

The basicity of the dioxide alters in the order
$C O_{2} < S i O_{2} < G e O_{2} < S n O_{2} < P b O_{2}$
The basicity increases on moving down the group. Thus, $C O_{2}$ and $S i O_{2}$ are purely acidic. $G e O_{2}$ is not as strongly acidic as $S i O_{2}$ . It is weakly acidic and weakly basic. $S n O_{2}$ and $P b O_{2}$ are definitely amphoteric.
