SUMMARY

The molecular formula for Chloroform is represented as CHCl3, which follows the convention in organic chemistry of placing carbon (C) first, followed by the attached atoms. While the formula Cl3CH conveys the same information, it is considered unconventional. This ordering aligns with the Hill system, which is a systematic way of writing chemical formulas. For further clarification, refer to the IUPAC Red Book, specifically chapter IR-4.4.

Homework Statement



I have to write the formula for Chloroform. As seen in this image:

Chloroform.jpg


Now I know it has 3 atoms of CL, 1 atom of C, and 1 atom of H.

I know the answer is CHCl3

But...why is that order. Why not Cl3CH ?

As far as I am aware, it is just the convention in organic chemistry to write the C and then follow with the things attached to that carbon. I don't think there is any reason to consider Cl3CH as incorrect (it still gives the same information as CHCl3), but maybe slightly unconventional?
