The rules for naming binary ionic compounds are as follows:
1. The metal keeps its name and is named and written first.
– For transition metals, we use Roman numerals to denote its charge.
2. The nonmetal keeps its base name but has its ending changed to –ide.
Rules for naming polyatomic ionic compounds:
(same as rule 1). Name the polyatomic ion as you would normally.
The rules for naming covalent (or molecular) compounds are as follows:
1. The first nonmetal is named normally and uses all numerical (Greek) prefixes except mono.
2. The second nonmetal keeps its base name but has its ending change to –ide. It will also use any of the numerical prefixes.
Choose the statements that are true about the differences of naming conventions for ionic and molecular compounds.
A) The systematic names of only ionic compounds can have a variety of endings (-ide, -ate, and -ite).
B) Binary molecular compounds end in -ide.
C) Only the systematic names of binary molecular compounds contain Greek prefixes.
D) There are no polyatomic group names used in generating the systematic name of a binary ionic compound.
E) None of the above
