Answer: The name of \(FeCl_2\) is iron (II) chloride.
Explanation:
\(FeCl_2\) is an ionic compound because iron element is a metal and chlorine element is a non-metal. The bond formed between a metal and a non-metal is always ionic in nature.
The nomenclature of ionic compounds is given by:
- Positive ion is written first.
- In case of transition metals, the oxidation state are written in roman numerals in bracket infront of positive ions.
- The negative ion is written next and a suffix is added at the end of the negative ion. The suffix written is '-ide'.
- In case of polyatomic ions, the name of the ion is written as such. For Example: \(OH^-\) is named as hydroxide, \(SO_4^{2-}\) is named as sulfate and so on..
Hence, the name of \(FeCl_2\) is iron (II) chloride.
