2) The basic nature of hydroxides of lanthanides increases from to
3) Most stable oxidation number shown by Lanthanides is + 3
The correct statements are
1) Lanthanides actively participate in chemical reactions
2) The basic nature of hydroxides of lanthanides increases from to
3) Most stable oxidation number shown by Lanthanides is + 3
The correct statements are
View answer and explanation
Correct option: D
1 and 3
Option D (1 and 3) is correct because lanthanides actively participate in reactions and primarily exhibit a +3 oxidation state, while the basicity of their hydroxides decreases across the series.
