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
Write the chemical formula for each substance mentioned in the following word descriptions (use the front inside cover of the textbook to find the symbols for the elements you dont know).
On treatment with hydrofluoric acid, silicon dioxide forms silicon tetrafluoride and water.
