"The obvious follow-up to SN1/SN2 substitution is a #ChemEd #Chemistry summary on E1/E2 elimination. This summary only looks at E1/E2 & not fun like E1cB. More detail is Enjoy (& yes a summary of which mechanism operates is coming next week). Enjoy https://www.makingmolecules.com/blog/eliminations https://www.makingmolecules.com/blog/eliminations"

"The obligatory summary of a summary and a table of E1 vs E2 vs Sn1 vs Sn2. Hopefully this is of use to some but if I'm brutally honest it was just a quick stop gap while I work on more fun #ChemEd #Chemistry summaries (currently writing ones on cycloadditions & rearrangements)"

"Today's #Chemistry #ChemEd summary is SN1/SN2 substitution. I waited for the 46th summary to cover this as I don't think it's as important as the chemistry of the carbonyl group (but is invariably introduced 1st in textbooks 🤷♂go figure).

"Not the summary I set out to draw. This was meant to be of next week's simplification of the rates of reaction. Never taught this so it's revision for me (I mention rates for SN1 but nothing else) so please tell me what to correct Hope it's useful #ChemEd #Chemistry #SciViz"

I'd do this one very differently if I did it again (which I will have as the resolution is poor & I'm not happy with it). Hopefully still has some use.

"@sjwill99 Good catch I'll tidy up the sloppy wording (probably at the weekend as this was an old summary & not in Affinity Publisher so corrections are less straightforward than I'd like Of course I'd prefer it to be right in the first place.)"

"1st summary (from 2022) on every UGs favourite stereochemistry. This #ChemEd #Chemistry intro avoids point groups/symmetry elements. Let the argument begin about the use of stereocentre to describe the carbon of an alkene. Happy to correct if there is a better term. Enjoy 🫤"

"Re-inventing the wheel. Instead of a #ChemEd #Chemistry summary here is my attempt at a pKa (in H2O) scale. Values are taken from the Evans/Ripin & Hans Reich resources. If you want a table I recommend these. This was an attempt at a more visual representation of the same data"
