Consider the following statements in respect of lanthanides:
The basic strength of hydroxides of lanthanides increases from `La(OH)_3, " to Lu " (OH)_3`,
The lanthanide ions `Lu^(3+), Yb(2+) " and " Ce^(4+)` are diamagnetic.
Which of the statement(s) given above is/are correct?

A

1 only

B

2 only

C

both 1 and 2

D

Neither 1 nor 2

Text Solution

Verified by Experts

The correct Answer is:
B
Basic strength decreases from `La(OH)_3 "to" Lu(OH)_3`,. Hence, (1) is incorrect. The given ions contain no unpaired electrons and therefore, are diamagnetic. Hence, (2) is correct
