QAIPM-2001-Ch-2883: NEET 2001 Chemistry - Class 12 AIPM-2001-Ch-2883 Solution: Which of the following statement is not correct?
Which of the following statement is not correct?
Multiple Choice Options
- A is less basic than .
- B In lanthanide series ionic radius of ion decreases.
- C La is actually an element of transition series rather lanthanides.
- D Atomic radius of Zn and Hf are same because of lanthanide contraction.
Step-by-Step Verified Solution
In lanthanides the basic character of hydroxides
decreases as the ionic radius decreases.
La 3+ ions are larger than Li 3+ so it easily gives OH �
ion thus La(OH) 3 is more basic than Li(OH) 3 .
