Chloro/Chlorido?

[Anna Castaneda 2E]

In lecture, Lavelle said that for anionic ligands like chloride we drop the -ide and add -o but the textbook says to make it -ido. It says the same for other anions like sulfate -> sulfato, nitrite -> nitrito..
Is there a difference between the two? Are they used in different scenarios?

-o is the older name while -ido is the new IUPAC name. I believe they can both be used, but this class will tend to use -o. This can be found in Dr. Lavelle's worksheet in the notes section after the tables: https://lavelle.chem.ucla.edu/wp-conten ... pounds.pdf

Both are valid. IUPAC just decided to remove the exceptions of chloro, nitro, cyano, etc. to make nomenclature a bit easier. You can see their full reasoning here.

[Kayley Steele 3D]

Both are correct but in this class Dr. Lavelle uses -O. I believe you can use both and still be correct but he always uses the old naming technique of -O.
