HW 17.31 About alphabetic sequence in writing symbols and naming them

Postby Yinhan_Liu_1D » Sat Nov 05, 2016 3:55 pm

In homework 17.31

1) Why is the "aqua" in c) written as H20 not OH2? Does it matter

2) Why is it Na[Fe(OH2)2(C2O4)2] but not [Fe(C2O4)2(OH2)2]? I remember in the book, it says that the sequence of naming is different from the sequence of writing them down. (i.e. when writing them down, "C" is before "O", while when naming them, "aqua" is before "oxalato")

1) I think writing it as (OH2) is safer because that's how the book does it.
2) In naming you write the neutral ligands first (so OH2 first because it's neutral). Otherwise it's alphabetical, and if 2 ligands contain the same element the ligand with fewer elements comes first.
