A) l and III
B) II and III
C) II only
D) l and II
Correct Answer: B
Solution :
The basic character of hydroxides decreases from La \[{{\left( \text{OH} \right)}_{\text{3}}}\] to Lu\[{{\left( \text{OH} \right)}_{\text{3}}}\]. Due to smaller size of Lu. The Lu?OH bond attains more covalent character. La \[{{\left( \text{OH} \right)}_{\text{3}}}\] is the most basic among hydroxides of lanthanoids.
