Anyone can help me on the chemistry notation

Click For Summary

Discussion Overview

The discussion revolves around the notation used in chemistry, specifically the meaning of "Et" in the context of the compound (COOEt)2C. Participants explore the chemical nomenclature and the identification of the compound represented.

Discussion Character

  • Conceptual clarification

Main Points Raised

  • One participant expresses uncertainty about the meaning of "Et" in the chemical notation, suggesting it might be similar to "-R" which denotes various alkyl groups.
  • Another participant clarifies that "Et" stands for an ethyl group (CH3CH2-) and identifies (COOEt)2C as diethyl malonate.
  • A third participant acknowledges learning from the discussion, indicating the value of the clarification provided.
  • A fourth participant reiterates the clarification about "Et" and the identification of the compound, confirming the information received from others.

Areas of Agreement / Disagreement

Participants generally agree on the meaning of "Et" and the identification of the compound as diethyl malonate, though the initial uncertainty from the first post indicates that not all participants are familiar with the notation.

Contextual Notes

The discussion does not address potential limitations in understanding chemical notation or the assumptions made about familiarity with chemistry concepts.

Who May Find This Useful

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

Thank you, Ygggdrasil! I just got the same answer from other friends ...
