When naming we write the ligands in alphabetical order. When we write out the formula from a name, should we write the substances in alphabetical order or does it not matter?

Write the names of the ligands in the following order: neutral, negative, positive. If there are multiple ligands of the same charge type, they are named in alphabetical order.

I don't think writing the ligands in alphabetical order when writing the formula from the name matters.

At the review session we were told that when going from name to formula the order of the ligands does not matter.

It doesn't matter which way you write it, though you can write it from positive to neutral to negative charge. And if you encounter 2 atoms of the same charge then you can go by alphabetical.
Good to know: Metals are always put first when going from name to formula
