Naming Non-ionic Compounds
Rules to Live By
![Page 2: Naming Non-ionic Compounds Rules to Live By. Rule #1 The first element in the formula is named first, and the full element name is used](https://reader036.vdocuments.us/reader036/viewer/2022062717/56649e305503460f94b20814/html5/thumbnails/2.jpg)
Rule #1
• The first element in the formula is named first, and the full element name is used.
![Page 3: Naming Non-ionic Compounds Rules to Live By. Rule #1 The first element in the formula is named first, and the full element name is used](https://reader036.vdocuments.us/reader036/viewer/2022062717/56649e305503460f94b20814/html5/thumbnails/3.jpg)
Rule #2
• The second element is named as it would be if it was an anion.
– Ex. Cl would be “chloride” like before.

Rule #3
• Prefixes are used to tell the number of atoms in the formula.
– We will look at these in 2 more slides.

Rule #4
• The prefix mono- (meaning 1) is never used for the first element.
– Ex. CO2 is carbon dioxide, not monocarbon dioxide. Ever.

Let’s Do Acid!In the learn-how-to-name-them sense…

Naming Acids1. If the anion does not contain oxygen,
the acid is named with the prefix hydro- and the suffix -ic.
Acid Anion Name .
HCl Cl-
HCN CN-
H2S S-2
hydrochloric acidhydrocyanic acid
hydrosulfuric acid
![Page 11: Naming Non-ionic Compounds Rules to Live By. Rule #1 The first element in the formula is named first, and the full element name is used](https://reader036.vdocuments.us/reader036/viewer/2022062717/56649e305503460f94b20814/html5/thumbnails/11.jpg)
Naming Acids
2. When the anion contains oxygen, we add either –ic or –ous to the end.
-ic we use when we have an anion whose name ends in –ate:
Acid Anion Name .
H2SO4 sulfate
H3PO4 phosphate
HC2H3O2 acetate
sulfuric acid
phosphoric acid
acetic acid

Naming Acids
-ous we use when we have an anion
whose name ends in –ite.
Acid Anion Name .
H2SO3 sulfite
HNO2 nitrite
sulfurous acid
nitrous acid

Acid (starts with H and is not water)
The anion (-) name ends in…
-ide
Single element from the periodic table: Br, Cl, I, S…
“Hydro_______ic Acid”
-ite
Only polyatomic ions
“_____ous Acid”
-ate
Only polyatomic ions
“_____ic Acid”
