Which hydrogen halides react with group 14 oxides?
All reactions taken from this site.
First some maths: 4 hydrogen halides can react with 5 Group 14 monoxides and dioxides. So, there should be 40 different chemical reaction combination possible. But not all reactions are feasible.
HF

With $\ce{SiO2}$ (already mentioned)

$$\ce{GeO2 + 4HF → GeF4 + 2H2O}$$

$$\ce{SnO + 2HF -&gt;[333 K] SnF2 + H2O}$$


HCl

$$\ce{GeO2 + 4HCl(g) -&gt;[450-500 C] GeCl4 + 2H2O}$$

$$\ce{GeO2 + 4HCl(l) -&gt;[170-180 C] GeCl4 + 2H2O}$$

$$\ce{SnO + 3HCl → H[SnCl3] + H2O}$$
$$\ce{SnO2 + 6HCl → H2[SnCl6] + 2H2O}$$
$$\ce{PbO + 2HCl → PbCl2 + H2O}$$
$$\ce{PbO2 + 4HCl → PbCl2 + Cl2 + 2H2O}$$

$\ce{HBr}$ and $\ce{HI}$ do not show such type of reaction.
