The most basic hydroxide from following ...

The most basic hydroxide from following is

A

`Pr(OH)_(3)(Z=59)`

B

`Sm(OH)_(3)(Z=62)`

C

`Ho(OH)_(3)(Z=67)`

D

`La(OH)_(3)(Z=57)`

Text Solution

Verified by Experts

The correct Answer is:
D
Due to lanthanoid contraction, the basic character of hydroxides decreases from `La^(3+)` to `Lu^(3+)`
As a result, covalent nature of Ln - OH bond also increases. Thus the most basic hydroxide among the gicen option is `La(OH)_(3)`.
