Question

What is the name of \[C{{o}_{3}}{{N}_{2}}\] ?

Answer 1

Hint: We know that IUPAC nomenclature is widely used in many forms of chemistry. IUPAC is the International Union of Pure and Applied Chemistry. To answer these kinds of questions we need to know all the rules on how to name a coordinated compound. Detailed explanation is given below.

Complete answer:
A complex is a substance wherein a metal atom or ion is related to a gathering of neutral atoms or anions called ligands. Coordination mixes are neutral substances like Cobalt is in the d-block of elements, so it is a transition metal. Cobalt has a common charge of \[+\text{ }2\] as in this compound. Nitrogen has a common charge of \[-3\]as in this compound Cobalt nitride would be the common name of the compound.
Here are the steps for deriving the name of a compound of a transition metal.
-Write the name of the transition metal. This gives: "cobalt".
-Add the name of the nonmetal with the ending "-ide". This gives: "cobalt nitride".
-Use the charge on the non-metal to find the charge on the transition metal. Each \[N\] needs three electrons to complete its octet. Thus each N ion has a charge of \[-3\], and the total charge on the two \[N\] ions is \[-6.\]
-Write the charge on the non-metal as Roman numerals in parentheses immediately after (no spaces) the name of the metal. This gives the name: \[\left( II \right)\]cobalt nitride.
Therefore, the total charge on the three \[Co\] ions is \[+6.\] Hence, each \[Co\] ion has a charge of \[+2.\]

Note:
Remember that the chemical formula of an ionic compound or a covalent compound tells us the ratio of the elements present in it. The valency of an atom or ion is the number of electrons it shares, loses or gains during a chemical reaction to attain stability, that is the number of bonds it forms.
