The rules for naming covalent compounds are as follows:
1. The first nonmetal is named normally and uses all numerical 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.
The numerical prefixes are:
Mono – 1 Di – 2
Tri – 3 Tetra – 4
Penta – 5 Hexa – 6
Hepta – 7 Octa – 8
Nona – 9 Deca – 10
Rules for Naming Binary Acids:
a. The prefix will be hydro-
b. Use the base name of the nonmetal (anion)
c. The suffix will be -ic acid
Rules for Naming Oxyacids or Oxoacids:
a. If the polyatomic ion ends with -ate then change the ending to -ic acid
b. if the polyatomic ion ends with -ite then change the ending to -ous acid
