Homework Help: *Simple Molecular Formula question - Thanks

  1. Apr 25, 2012 #1
    1. The problem statement, all variables and given/known data

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


    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 ?

    2. Relevant equations

    3. The attempt at a solution

    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?
