Category:Set index articles on molecular formulas

To add an article to this category, please use {{Molecular formula index}}.

Pages in this category are normally organic compounds, and are arranged overall in order of increasing numbers of carbon atoms:

#Cs Group
1 1
2 2
3 3
4 4
5 5
6 6
7 7
8 8
9 9
10-15 A
16-19 B
20-29 D
> 29 E

Within groups having the same carbon count, the order is fairly intuitive, but the following exceptions have been noted:

This always pops up when only one atom of a kind is present: that entry will appear at the bottom of the list below all the others. For the same reason you will find C10H.... preceding C2H..... .

The situation arises as the sorting algorithm is based on the ASCII code of letters and numbers. As numbers have lower codes than letters, this counterintuitive situation arises.
