Out of Lu(OH)_(3) and La(OH)_(3) which is more basic and why? |
|
Answer» SOLUTION :(i) As we move from `Ce^(3+)` to `Lu^(3+)`, the BASIC character of `Lu^(3+)` IONS decreases. (ii) Due to the DECREASE in the SIZE of `Lu^(3+)` ions, the ionic character of Lu-OH bond decreases, covalent character increases which results in the decrease in the basicity, (iii) Hence, `La(OH)_(3)` is more basic than `Lu(OH)_(3)` |
