Hint: In order to get this question right, the first thing to know is about the structure of Potassium cuprochloride. We know that Potassium cuprochloride is a coordination compound so the structure for the same is \[{{K}_{3}}[CuC{{l}_{4}}]\].
Complete Step by Step Solution:
Molecules with one or more metal centres that are linked to ligands are known as coordination compounds. Complexes like these might be neutral or charged. Neighbouring counter-ions help to stabilise the complex when it is charged.
A metal ion is located in the middle of a complex ion, which is surrounded by various other molecules or ions. These can be thought of as being joined to the centre ion by coordinate bonds, however the bonding is sometimes more intricate than that. Ligands are the ions or molecules that surround the metal ion in the centre. The following is a description of the normative guidelines that must be adhered to when naming coordination compounds:
In the nomenclature of complicated coordination complexes, the ligands are always written before the main metal ion.
The letter "o," which typically takes the place of the letter "e," must terminate the names of the anions that are present in a coordination complex. The chloride anion must be expressed as "chlorido," and the sulphate anion must be written as "sulfato."
The name of the principal metal atom is written after the ligands have been identified. The prefix "-ate" is added if the complex carries an anionic charge.
Roman numerals contained in a set of parentheses must be used to indicate the oxidation state of the central metal atom/ion. The cationic entity must be written before the anionic entity if the coordination molecule is accompanied by a counter ion.
After understanding all the rules for the IUPAC, we can name the compound
\[{{K}_{3}}[CuC{{l}_{4}}]\] as: \[Potassium\text{ }tetrachlorocuprate\text{ }\left( I \right)\]
Hence, the correct option is B. \[Potassium\text{ }tetrachlorocuprate\text{ }\left( I \right)\]i.e. the IUPAC name of Potassium cuprochloride is \[Potassium\text{ }tetrachlorocuprate\text{ }\left( I \right)\]
Note: To solve these types of questions, you should have a good knowledge of coordination compounds in order to make the structure and further remember the IUPAC rules for giving the correct name for the compound.
