Anyone can help me on the chemistry notation

  1. Jul 29, 2011 #1
    I encountered a chemical (COOEt)2C, and I don't really know what does Et mean. I am not familiar with chemistry, but I guess this is something similar to -R which stands for -CH3, -CH2CH3 etc. Could anyone help to explain?

    Thanks you very much.

    Et represents an ethyl group, CH3CH2-

    (COOEt)2C represents the compound diethyl malonate
