Question

formula of the complex triamminetrinitrito-o-cobalt(iii)

Answer 1

Explanation:

Formula of triammidenitrito-O-cobalt(III) is [Co(NH3)3(ONO)]²+

Additional information :-

For making structure of complex :-

Step 1 :-

we know that ammide is the IUPAC name of NH3 and nitrito-O is IUPAC name of ONO.

Step 2 :-

we know that metal name is written in English in Cationic complex. So, it's cleared that this complex is cationic complex.

Step 3 :-

Making structure :-

metal + ligan + O.N.(oxidation number)

Here,

• metal is Co
• ligan is NH3 and ONO

[ Co(NH3)3(ONO) ]^n

Let's calculate the value of n :-

It's cleared in question that O.N. of Co is 3

Then,

3 + 0 × 3 + (-1) = n

⇝n = 3 - 1

⇝n = 2

Hence,

The Formula is [ Co(NH3)3(ONO) ]²+
