Which of the following statement is not correct?A. `La(OH)_3` is less basic than `Li(OH)_3`B. In lanthaniode series, ionic radius of `Ln^(3+)` ion decreases.C. La is actually an element of transition series rather than lanthaniodes.D. Atomic radius of Zr and Hf are same because of lanthaniode contraction.

Answer» Correct Answer - A
`La(OH)_3` is more basic than `Li(OH)_3` In lanthaniodes the basic character of hydroxides decreases as the ionic radius decreases.
