Assign reasons for the following: (i) Copper(I) ion is not known in aqueous solution. (ii) Actinoids exhibit greater range of oxidation states than lanthanoids. |
|
Answer» SOLUTION :(i) Copper(I) ion does not have a sufficiently negative value of enthalpy of hydrogen. And Cu(I) ion DISPROPORTIONATES in aqueous solution as `2Cu^(+)toCu^(2+)+Cu` (ii) DUE to comparable ENERGIES of 5f, 6d and 7s sub-shells, all the electrons PRESENT in these sub-shells participate in bonding, resulting in large number of oxidation states for actinoids. |
