Question

lower oxidation states of heavier members of group 6 of transition series are more stable
​

Answer 1

Explanation:

(d) Lower oxidation states of heavier members of group-6 of transition series are more stable. Answer: (b, c) In d-block elements, for heavier elements, the higher oxidation states are more stable. Hence, Mo(VI) and W(VI) are more stable than Cr (VI).
