JEE Main 2024 — p Block Elements (Group 13 & 14) Question with Solution

All members of group 14 when heated in oxygen form oxides. There are mainly two types of oxides, i.e., monoxide and dioxide of formula $\mathrm{MO}$ and ${\mathrm{MO}}_2$ respectively. $\mathrm{SiO}$ only exists at high temperature. Oxides in higher oxidation states of elements are generally more acidic than those in lower oxidation states. The dioxides ${\mathrm{CO}}_2, {\mathrm{SiO}}_2$ and ${\mathrm{GeO}}_2$ are acidic, whereas ${\mathrm{SnO}}_2$ and ${\mathrm{PbO}}_2$ are amphoteric in nature. Amongst monoxides, $\mathrm{CO}$ is neutral.

Hence option C is the answer.
