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

COMMON NAMES
Using the rules for naming binary
molecular compounds, describe
how you would name N2O4.
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.
1.
Yes 2=di
Dinitrogen
O-oxygen = oxide
4=tetra
Tetroxide
Dinitrogen tetroxide
Acids
ACIDS
Oxyacids
Binary
Acids
OxyANION root – ic + Acid
Hydro + element-ic + acid
H2SO4
HCl
Sulfuric Acid
Hydrochloric 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.
