### Naming

Has anyone found an easy way to remember how to name molecules?

### Re: Naming

There are different naming conventions for different types of molecules. Here are the very basic rules

Ions:
"Cation Name" "Anion Name + ide"
ex.) $NaCl$: Sodium Cholride

Covalently Bonded Molecules:
"Central Atom's Name" "Greek Suffix + Peripheral Atom's Name + ide"
ex.) $CF_{4}$: Carbon Tetrachloride

Coordination Compounds:
"Greek Prefix + Ligand's Name" (if multiple ligands organize in alphabetical order) "Tansition Metal Cation's Name + Roman Numeral" "Anion's Name (if present" "Hydrate (If present)
ex.) $[Co(NH_{3})Cl]Cl\cdot 2H_{2}O$: Pentaamine chloro cobalt (II) cholride dihydrate

To add onto the coordination compounds, if the compound as a whole is negatively charged, you want to add an -ate to the ending of the central atom instead.

### Re: Naming

In order to begin, look at the name of the ligands first for coordination compounds. Using the number of ligands, you should use mono-, di-, tri-, tetra-, penta-, or hexa-. Add an o to the end of an anion name, like cyanide s cyan. You should also look at the metal to be placed at the end of the name in alphabetical order. Roman numerals for the metal should be based on the oxidation of the whole molecule with ligands.
