Lanthanides does not show +4 O. S. in which of the following configura – InterviewSolution

1.	Lanthanides does not show +4 O. S. in which of the following configuration
Answer» `f^(0)` `f ^(7)` `f ^(14)` all of these Solution :Lanthanides show +4 O.S. in `f ^(0), and f^(7)` CONFIGURATION, whereas it is POSSIBLE to attend stable electronic configuration. i.e., `(+3` to `+4`) But they does not show +4 O.S. in `4f^(14)` configuration because, by lose of three electrons they already ACQUIRE `4f^(14)` configuration i.e. `(+3` to `+4)` O.S. Hence `+4` O.S. is not possible in `4f^(14)` configuration.
