The lanthanide contraction is responsible for the fact that
(a)Zr and Yt have about the same radius
(b)Zr and Nb have smaller oxidation state
(c)Zr and Hf have about the same radius
(d)Zr and Zn have the same oxidation state.

A

`Zr` and `Y` have about the same radius

B

`Zr` and `Nb` have similar oxidation state

C

`Zr` and `Hf` have about the same radius

D

`Zr` and `Ce` have the same oxidation state.

Text Solution

Verified by Experts

The correct Answer is:
C
Due to poor shielding of `(n-2)` f-electrons, size of `Zr` and `Hf` remain same.
