Single Choice
The trivalent ion having largest size in Lanthanide series is:
A$$Ti$$
B$$Zr$$
C$$Hf$$
D$$La$$
Correct Answer
Solution
The Lanthanide series starts from $$La$$ and thus $$La^{3+}$$ will have the largest size because we know on moving across the period from left to right the size decreases in Lanthanide and thus the same will be similar for the trivalent ions.
Hence, the correct option is $$(D)$$
