An oxide X in its normal form is almost non – reactive due to very high X – O bond enthalpy. It resists the attack by halogens, hydrogen and most of acids and matals even at elevated temperatures. It is only attacked by HF and NaOH The oxide X is.

A

SiO2SiO_{2}

B

CO2CO_{2}

C

SnO2SnO_{2}

D

PbO2PbO_{2}

Answer

SiO2SiO_{2}

Explanation

Solution

: SiO2SiO_{2}is attacked by HF and NaOH but not by chemicals under normal conditions.
