Give the systematic names of these compounds. spelling counts! (a) cui(s) (b) fe2o3(s) (c) cof2(s) (d) feo(s)

Respuesta :

Answer : The name of the compounds are,

[tex]CuI(s)[/tex] = Copper(I)iodide

[tex]Fe_2O_3(s)[/tex] = Iron(III)oxide

[tex]CoF_2(s)[/tex] = Cobalt(II)fluoride

[tex]FeO(s)[/tex] = Iron(II)oxide

Explanation :

Naming rules for the compounds :

  • write the cation name first then name the anion.
  • If the cation is the transition metals with various charges, write the charge by using parenthesis and Roman numerals after the metal name.
  • For mono-atomic anions, use suffix (-ide).

The Systematic name for CuI is Copper(I) iodide

The Systematic name of a compound is also called the (IUPAC) (International Union of Pure and Applied Chemistry) nomenclature which tells the  the chemical structure of the chemical substance,  information about the  chemical properties and  creates  consistency.

Now in naming the compounds below:

  • if the compound contains  molecular ( with non metals ) and ionic ( metals )compounds, the name of the second compound should end in ‘ide’
  • Ionic Compounds containing transition metals, should have  roman numeral after the name of the metal to indicate the charge of the  transition.

Hence,

(a) CuI(s) -Copper(I) iodide

(b) fe2o3(s)- Iron(III) oxide

(c) CoF2(s)-Cobalt(I I) fluoride

(d) FeO(s)- Iron(II) oxide
