Question

[Co(CO3)(NH3)4]+1 EAN​

Answer 1

Answer:

The EAN is 36.

Explanation:

The effective atomic number of the coordination compound is calculated as follows,

$EAN=Z-X+2n$     (1)

Where,

EAN=effective atomic number

Z=Atomic number of central metal

X=Oxidation state of the central atom

n=total number of ligands

The coordination compound given in the question is,

$[Co(CO_3)(NH)_4]^+^1$         (2)

Co=central metal atom

CO₃, NH₄=ligands

The total number of ligands in the given compound can be calculated as,

$n=2+4=6$        (3)

2=from CO₃ as it joins through two bonds

4=number of NH₃

The oxidation state of the central atom is calculated as follows,

$X-2+0=+1$        (4)

-2=contributed by CO₃

0=contributed by NH₃

+1=overall charge on the compound

So,

$X=1+2=3$         (5)

The atomic number of Co(Z)=27

By substituting the required values in equation (1) we get;

$EAN=27-3+2(6)$

$EAN=36$

Hence, the EAN of the given compound is 36.
