Naming for the final

Postby Dakota Walker 1L » Sun Dec 01, 2019 4:57 pm

Can someone summarize the general rules for naming we will need for the final?
I don't understand what we do and don't have to memorize/know.

Some of the general rules for naming are as follows. Use the prefixes di, tri, tetra, penta, hexa, octa, if there are two or more of certain molecules. For ligands, name them in alphabetical order remembering to replace ammonia with ammine, or anything ending in ide with an o. Also cations go first and anions have -ate at the end of them.

check out page 723 of the textbook!! but

naming goes: [greek prefix; ligand name(s, in alphabetical order); transition metal cation; Roman numeral]

the brackets represent coordination sphere
the greek prefix (di, tri, tetra, penta) refers ti how many of the ligand there is
the ligands have the endings of -o (instead of -ide, -ate, or -ite, you have -ido, -ato, -ito)
the Roman numeral is the charge of the cation which you figure out from the charge of the ligands and total charge, cation charge is the difference (if this charge is negative, you put -ate at the end of the cation name!!)

Neutral ligands have the same name except for a few. Water turns to "aqua," ammonia turns to "ammine," and CO turns to "carbonyl." Ligands that are anions end with o.

I assume there are exceptions to the naming rules, but do we need to be aware of any of them?
