Which of the following oxidise shows electrical properties like metals? (a) SiO2 (b) MgO (c) SO2 (d) CrO2

Answer»

Correct Answer is: (d) CrO2

CrO2, TiO and ReO3 are some typical metal oxides which show electrical conductivity similar to metal. While SiO2, MgO and SO2 are oxides of metal, semimetal and non-metal which do not show electrical properties.
