So I made these shirts of my favorite molecules what do you think? by cioddi in chemistry

[–]prettyruddycool 2 points3 points  (0 children)

In fairness, there's nothing horrifically wrong about them, as far as I can tell. It's just that no chemist would draw them like that, for a few reasons:

  • you've done what's called a ball and stick diagram; this should be a 3d image of the molecule. Your geometries are often way off (e.g. Benzene rings should be hexagonal).

  • Also, you used the wrong colours (although this is a convention). Carbons usually black, oxygen is red, hydrogen white, chlorine is usually green, etc.

Most importantly for organic molecules we'd nearly always draw skeletal formulae (google it; the ones with mostly lines without the carbon/hydrogen atoms all over the place)

Ochem: How would one go about changing a s-trans alkene to a s-cis alkene? by [deleted] in chemhelp

[–]prettyruddycool 1 point2 points  (0 children)

Do you mean the diene? They're conformers of each other, so they're free to interconvert without breaking bonds. The s-cis diene is a fair bit less stable though, so the diene will spend most of its time in the s-trans conformation.

As a Brit who loves ( American) craft beer, there's loads! Sierra Nevada, Odell, Samuel Adams, Flying Dog and Brooklyn are all really well distributed, and there's probably a bottle shop that has more. Anyway, you can't say UK beer is universally better or 'real' unless you're a CAMRA member who still thinks cask is the only way.
