Question

(iv) Identify complex ion in which effective atomic number of
the central metal ion is 35.
(Given At. number of Co = 27, Fe = 26, Zn = 30)
(a) [Zn (NH2),12+
(b) [Fe(CN)
(c) [Fe (CN);}}
(d) [Co (NH,
-4-​

Answer 1

The option (d) is correct.

Co(NH3)6

Because

27 + 8 = 35

Here,

Co = 27

NH3 = 8
