Select the total number of properties which are correct with respect to
`K_(4)[Fe(CN)_(5)O_(2)]` or any of its isomers (`d^(6)` configuration of central metal ion).
(a) Paramagnetic
(b) Inner orbital complex
(c ) Low spin complex
(d)`Delta_(0) gt P`
(e ) Shows optical isomerism
(f) Shows linkage isomerism

Answer

6

Explanation

`overset(+4)K_(4)[overset(+2)(Fe)(overset(-5)(CN))_(5)overset(-1)O_(2)],(a),(b),(c ),(d),(e ),(g)`
Also, consider linkage isomers for (e ).
