Vedclass · Answer

(D) The basicity of lanthanide ions depends on their ionic character. As the atomic number increases from $La$ to $Lu$, the ionic radius decreases due to lanthanide contraction. As the size of the cation decreases, the covalent character increases and the ionic character decreases. Therefore, the basicity decreases as the ionic radius decreases. The correct order of basicity is $La^{3+} > Ce^{3+} > Eu^{3+} > Lu^{3+}$.

The correct basicity order of the following lanthanide ions is
