प्रश्न

Assertion: \[\ce{Cu^2+}\] iodide is not known.

Reason: \[\ce{Cu^2+}\] oxidises \[\ce{I^-}\] to iodine.

पर्याय

  • Both assertion and reason are true, and reason is the correct explanation of the assertion.

  • Both assertion and reason are true but reason is not the correct explanation of assertion.

  • Assertion is not true but reason is true.

  • Both assertion and reason are false.

उत्तर

Both assertion and reason are true, and reason is the correct explanation of the assertion.

Explanation:

All halogens combine with copper to form copper halides except iodine. The reason behind this is that \[\ce{Cu^2+}\] oxidises iodide (-1) to iodine (0). Therefore, \[\ce{Cu^2+}\] iodide does not exist .Both the statements assertion and reason are correct and reason is the correct explanation of assertion.
