What is a binary molecular compound?
A compound containing only two different types of atoms that are COVALENTLY bonded
N2O

Using the rules for naming binary molecular compounds, describe how you would name N2O4.
1. Element on the left does it need a prefix. If yes assign it.
2. Identify second element and change ending to ide.
3. Assign prefix to second element.
Yes 2=diDinitrogen
O-oxygen = oxide
4=tetraTetroxide
Dinitrogen tetroxide
Acids
ACIDS
Oxyacids Binary Acids
Hydro + element-ic + acid
HCl
Hydrochloric Acid
OxyANION root – ic + Acid
H2SO4
Sulfuric Acid
What is the difference between a binary acid and an oxyacid?
Binary acids contain hydrogen and one other element, they are named with the prefix hydro- and the root of the other element with the suffix –ic acid
Oxyacids contain oxygen bonded to another non-metal element, they are named based off the OXYANION that they are formed from.
