Explainwhyoxidationstatesof transitionelementsincreases firstfrom Sc to Mn andthendecrease ? |
|
Answer» SOLUTION :(i) Theuse of3d electronfor formation ofbondincreasesfrom SC to Mn causingthe INCREASESIN oxidationstateupto +7 . (ii) Thereasonfor Mnhavinghighestoxidationstateof +7is due tothe presenceof 7 unpairedelectronsin itsatom. (III)As thenumberof unpairedelectrons decreasesfrom Feto CU .sothere is thedecrease in oxidation state. |
