Iron(III) hexacyanoferrate(II)
(b) What type of isomerism is exhibited by the complex
(c) Write the hybridisation and number of unpaired electrons in the complex
Solution:
(a) Fe 4 [ Fe ( CN ) 6 ] 3
(b) Ionization isomerism.
[ Co ( NH 3 ) 5 SO 4 ] Cl and [ Co ( NH 3 ) 5 Cl ] SO 4
(c)[ COF 6 ] 3 −
In this complex, Co possesses +3 oxidation state.
Co 3 + = 3 d 6 F − = 4
(b) Ionization isomerism.
(c)
In this complex, Co possesses +3 oxidation state.
Since
Number of unpaired electrons
