Each of the following compounds is incorrectly named. What is wrong with each name, and what is the correct name for each compound?
a. FeCl3, iron chloride b. NO2, nitrogen(IV) oxide
c. CaO, calcium(II) monoxide
d.Al2S3, dialuminum trisulfide
e. Mg(C2H3O2)2, manganese diacetate
Solution:
a. FeCl3, iron chloride - roman numeral is missing since Fe is a transition metal. The name should be iron(III) oxide
b. NO2, nitrogen(IV) oxide - this is a covalent compound and should be named using prefixes. Nitrogen dioxide
c. CaO, calcium(II) monoxide - since calcium is not a transition metal, no roman numeral is needed. Calcium oxide
d.Al2S3, dialuminum trisulfide - this is an ionic compound. Aluminum sulfide
e. Mg(C2H3O2)2, manganese diacetate - this is an ionic compound that consists of a metal and a polyatomic ion. Magnesium acetate.
