Assign a reasons for the following . (i) Copper (I) ion is not known to exist in aqueous solutions. (ii) Both `O_(2)` and `F_(2)` stabilize high oxidation states of transition metals but the ability of oxygen to do so exceeds that of fluorine. |
|
Answer» (i) Cu (I) are unstable in aqueous soluton and under go disproportionation `2Cu^(+) to Cu^(2+) + Cu` `Cu^(2+)` is stable due to more (-) ve `Delta_("Hyd")H` of `Cu^(2+)`(aq) that compensate the 2nd I.E. of Cu. (ii) This is due to the tendency of oxygen to form multiple bonds. |
