Which of the following order of radii is INCORRECT -
Options:
Answer:
C
Solution:
A is correct: Sc < Y < La. B is correct: Ti < Zr approximately equals Hf because of lanthanide contraction. C is incorrect because radii do not decrease Sc > Y > La; they increase down the group. D, Sc < La > Y, correctly states that La is larger than both Sc and Y. Therefore only C is incorrect; answer C.
