AIIMS 2019 Chemistry Oxidation States MCQ Question
Assertion : Oxidation state of in , is by conventional method is wrong.
Reason : Because the maximum oxidation state of can not be more than since it has 5 electron in orbital and one electron in orbital.
If both assertion and reason are true and reason is the correct explanation of assertion.
If both assertion and reason are true but reason is not the correct explanation of assertion.
If assertion is true but reason is false.
If both assertion and reason are false.
Correct Answer
Detailed Explanation
In CrO₅, the chromium (Cr) atom has an oxidation number of +6, which corresponds to its maximum oxidation state due to its six valence electrons. This is consistent with the fact that Cr can exhibit oxidation states ranging from 0 to +6, and +6 is the highest it can achieve. The other options are not applicable as they do not provide any relevant information or alternative answers regarding the oxidation state of chromium in CrO₅. Understanding oxidation states is crucial for predicting the behavior of elements in various chemical reactions and compounds.
