Question

Which of the following statements is not correct? (A)  La(OH)3 is more basic than Lu(OH)3  (B)  Zr4+ and Hf4+ possess almost same ionic radii (C)  Ce4+ can act are reducing agent (D) In lanthanide series, ionic radius of Ln3+ ions increase

Tardigrade Admin · Accepted Answer

The ionic and atomic radii decreases from La to Lu due to lanthanoid contraction.

Q. Which of the following statements is not correct?

$L a (O H)_{3}$ is more basic than $Lu (O H)_{3}$

$Z r^{4 +}$ and $H f^{4 +}$ possess almost same ionic radii

$C e^{4 +}$ can act are reducing agent

In lanthanide series, ionic radius of $L n^{3 +}$ ions increase
