I would like a proof for that an achiral molecule that consists of two similar components and two other distinct components are always superposable as for example glycine. I would believe I visual proof would be the most easy approach for me. Thank you! An image of glycine is in the attachment as an illustration.

This solution clearly defines what an achiral molecule is, with the help of two examples. And then this solution explains why glycine is achiral, with the help of a model. This solution will be an excellent guide for visualizing and conceptualizing similar problems.
Visual proof of superposability for a distinct molecule

You are right! Visualization is the key to these kind of problems. Often time a model in ...

- "Thankyou for the feedback. I have a few question though; With the first statistic about cost below... “According to Sigma-Aldrich catalog, cost of 1L octane is AUD $ 392.00, whereas the cost of 1L ethanol is AUD $196.00. Moreover, if ethanol is obtained from sugar industry as a by-product, it may cost even less. Source of oxygen is ambient atmosphere, so it costs nothing. So ethanol is much cheaper than petrol, in fact it is half-priced: AUD $ (392-196) = $ 196.” I didn't think it made sense because the cost of petrol per litre is normally a dollar something or even less than a dollar not a couple of hundred of dollars. For example, a statistic that I found in america was: "U.S. ethanol production costs are about $1.20 per gallon of ethanol, or $1.82 per gallon on a gasoline-equivalent basis." However, I was wondering whether you could find an Australian statistic. Also, you mentioned that H20 is not a greenhouse gas. However, in the combustion equations it is actually carbon dioxide and water vapour which are produced and they are both greenhouse gases. Finally, how do I calculate the energy efficiency of ethanol and petrol? "
- "Thank you!"
- "Didnt really answer my questions but gave me a start at least."
- "Once again this is tremendous help I can't thank you enough for not only working the problem but explaining in detail how and why!! KR"
- "Awesome thank you so much for the help!!!"
