Assertion: Higher oxidation states in transition metals are more covalent than lower oxidation states.
Reason: Higher oxidation states involve more d-electrons than lower oxidation states.
Reason: Higher oxidation states involve more d-electrons than lower oxidation states.
View answer and explanation
Correct option: A
Both assertion and reason are correct statements, and reason is the correct explanation of the assertion.
Option A (Both assertion and reason are correct statements, and reason is the correct explanation of the assertion) is correct because higher oxidation states lead to greater polarization and thus more covalent character.
