Tl(OH)_3 is less basic than TlOH. Why ?

Answer»

SOLUTION :`Tl(OH)_3` is less basic than TLOH, as the polarising power of `Tl^(3+)` is more than `Tl^(1+)`.
`Tl-O` BOND in `Tl(OH)_3` becomes STRONGER than that in `TlOH.` As Tl-O bond becomes stronger, release of `OH^(-)` ion becomes less POSSIBLE. Hence basic nature of `Tl(OH)_3` is less.
