Across the lanthanide series, the basicity of the lanthanide hydroxides

Question

Across the lanthanide series, the basicity of the lanthanide hydroxides (A) increases (B) decreases (C) first increases and then decreases (D) first decreases and then increases

Tardigrade Admin · Accepted Answer

Basicity of lanthanide hydroxides decreases along the lanthanide series from left to right. This is because size decreases from left to right due to lanthanide contraction. This results in increased covalent character of M-OH bond.
