Question

van-Arkel method is used to prepare samples of some metals. It involves reaction of $CO$ with metals to form volatile carbonyls which decompose on heating to give pure metal.

A

Both Assertion and Reason are true and Reason is the correct explanation of Assertion

B

Both Assertion and Reason are true but Reason is not the correct explanation of Assertion

C

Assertion is true but Reason is false

D

Both Assertion and Reason are false

Answer

Assertion is true but Reason is false

Explanation

Solution

van-Arkel method involes use of $I_{2}$ to form volatile iodide of metals which on decomposition gives pure metals.
