Question

@ The coordination number of cobalt in [Co(en)( H2O)4]3+ is
a. 5
b.3
c . 6
d 4​

Answer 1

Answer:

Solution

Explanation:

6 is right option

ok

Answer 2

The number of co-ordinate bonds in the coordination sphere of the central atom with the ligands is known as the Coordination number.

In the given complex,

Co binds with a bi-dentate  ethylenediamine ( 2×1)

It also binds with four mono-dentate  H20 (4×1)

Therefore, the co-ordination number of Co in the complex

[Co(en)( H2O)4]³⁺ will be given by 4 +2 = 6

Hence, its coordination number is 6.

The correct option is c) 6.
