which of the following oxides shows electrical properties like metals ?

A

`SiO_(2)`

B

`MgO`

C

`SO_(2)(s)`

D

`CrO_(2)`

Text Solution

Verified by Experts

The correct Answer is:
D
`CrO_(2),TiO` and `ReO_(3)` are some typical metal oxides which show electrical conductivity similar to metal. While `SiO_(2),MgO` and `SO_(2)` are oxides of metal, semimetal and non-metal which do not show electrical properties.
