Molecular Compounds: Naming
The names of molecular compounds include prefixes to indicate the numbers of atoms in the molecular formula
These prefixes are the same ones used for hydrates!
How to know when a compound is an acid
is an acid if its chemical formula starts with one or more hydrogen atoms and has the aqueous state symbol (aq)
-Water is an exception to this rule!
TRUE OR FALSE: Acids act like…molecular compounds until they are dissolved in water
TRUE
Once dissolved, they break apart into ions like an ionic compound would!
Binary acids
If the formula of the acid does NOT include oxygen
How to name binary acids:
Start with the prefix hydro- and end with -ic acid
Oxyacid
If the formula does include oxyge
How to name an Oxyacid
Name is based on the anion, and does NOT start with hydro-
How to name an Oxyacid: x + 1

How to name an Oxyacid: x – 1
Anion name: ____ite
Acid name: ____ous acid
How to name an Oxyacid: x – 2
