What are the systematic names of these ?
1. CuI (s)
2. CoF2 (s)
copper(I) iodide
cobalt(II) fluoride
To determine the systematic names of these compounds, we need to follow the rules of chemical nomenclature. Here's how you can derive the systematic names for each of the compounds you provided:
1. CuI (s):
The first step is to identify the elements present in the compound. In this case, we have copper (Cu) and iodine (I).
Next, we need to determine the oxidation states of each element. Copper is known to have multiple oxidation states, but in this compound, it only has one possible oxidation state, which is +1. Iodine tends to form an anion with a charge of -1.
To name this compound, we use the naming convention for ionic compounds. The cation (Cu+) is named simply as "copper," while the anion (I-) is named as "iodide." Combining the names together, we get the systematic name "copper(I) iodide."
2. CoF2 (s):
In this compound, we have cobalt (Co) and fluorine (F).
Cobalt can have multiple oxidation states, and in this case, it has an oxidation state of +2. Fluorine typically has an oxidation state of -1.
Following the rules for naming ionic compounds, we name the cation (Co2+) as "cobalt" and the anion (F-) as "fluoride." Combining these names, the systematic name for this compound is "cobalt(II) fluoride."
In summary:
1. CuI (s) is called "copper(I) iodide."
2. CoF2 (s) is called "cobalt(II) fluoride."
Remember, when naming compounds, it is important to identify the elements, determine their oxidation states, and then combine the names following the appropriate naming conventions.
The systematic names of the given compounds are:
1. CuI (s) - Copper(I) iodide
The compound consists of copper (Cu) and iodine (I) ions, so the systematic name is copper(I) iodide.
2. CoF2 (s) - Cobalt(II) fluoride
The compound contains cobalt (Co) and fluorine (F) ions with a charge of 2, so the systematic name is cobalt(II) fluoride.
