9C.1 7th edition alphabetical order when naming

Postby Nawaphan Watanasirisuk 3B » Sat Dec 01, 2018 5:52 pm

On the question 9C.1 part c) why is the answer aquapentacyanocobaltate and not pentacyanoaquacobaltate ? I thought we rank the ligands based on their name on the periodic table. Did I remember wrong and we actually rank the alphabetical order based on their actual name?

The ligand names should be in alphabetical order.

The order within the formula and when writing the actual name may be different. The alphabetical order of the ligands when written out for the naming is independent of the alphabetical order when writing out the formula.
