Part 2 of my rates of reaction summary. Still outside of my comfort zone (help physical chemists!). Here are reaction profiles, mechanisms & rate laws. Hopefully, it gives an idea of the connection between mechanism & rate law (but also how the rate laws can quickly get complicated). Next week's full blog post will have a method to write the third order rate law for the amide hydrolysis.
I hope this of use to #UG.
Enjoy

Not the summary I set out to draw. Here is a muddled overview of collision theory for the rates of reaction. This was meant to be the bottom third of what will now be next week's organic chemist's simplification of the rates of reaction.
For 24 years, I have managed to avoid teaching this subject, so this is a bit rough but I hope it has some use (just don't show a physical chemist). Hope it is useful for #ChemEd #Chemistry #SciViz #chemiverse & please tell me what to correct!

The full summary of conjugate additions is now available at https://www.makingmolecules.com/blog/conjugate
This is the wordy/full explanation of last week's #chemistry #ChemEd #SciViz 1 page summary here: https://mas.to/@nz_molecules/110853110729548480
Hope at least one of them is useful

The blog version ofhttps://mas.to/@nz_molecules/110728502902113734 is now available at www.makingmolecules.com/blog/benzyne These actually get written before the #ChemEd #Chemistry #SciViz to gather my thoughts (but get published afterwards as they are never as popular & I'm a sucker for a popular post 😉)

Who knew there were so many ways to achieve nucleophilic aromatic substitution? With stunning originality & a fair amount of flair, I present 'Nucleophilic Aromatic Substitution 3'. This #chemistryeducation #Chemistry #SciViz 1-pager covers substitution through the formation of benzyne intermediates. It is a #UG summary. It doesn't cover all the elegant chemistry of arynes (the blog version (next week) will include references to good reviews). As always, I hope this is useful ...

After 2 weeks of #SciViz #ChemEd #Chemistry 1 page pictorial summaries of SNAr here https://mas.to/@nz_molecules/110615477224228595 & https://mas.to/@nz_molecules/110649344802235176 I've added the full (wordy) explanation at www.makingmolecules.com/blog/nucleophilicaromaticsubstitution The summaries are meant to jog the memory. The blog is for those that need more of an explanation. It has many more words (and more pictures (normally, it is the trial run for the 1 page summaries)).
Hopefully it is useful

The second #ChemEd #SciViz #chemistry 1-pager about nucleophilic aromatic substitution. Reactions of diazonium salts & Sandmeyer reaction. Hopefully helpful for #UG ... & if anyone has tips on nitrile formation by the Sandmeyer, I'd be grateful as we have one (involving [2.2]paracyclophane) that ain't working! #Chemiverse

The predictable follow up to electrophilic aromatic substitution is...wait for it... a #SciViz #ChemEd #Chemistry 1pager about nucleophilic aromatic substitution. This one looks at the most common #UG variant, the addition-elimination mechanism. As always I hope it useful. Enjoy!

Takashi Kawase has released a #linux version of VVDViewer (https://github.com/JaneliaSciComp/VVDViewer), a powerful volume renderer (#scivis, #sciviz) for #fluorescence #microscopy data. To celebrate, here is a video rendered by VVDViewer as driven by the Linux version of neuVid. The input to neuVid is a high-level description of the video, in this case showing four #drosophila lines from the #HHMIJanelia FlyLight Gen1 MCFO collection. The input text is pretty simple...

As is tradition, after the pretty #chemistry #SciViz 1pagers https://mas.to/@nz_molecules/110501915777666980 & https://mas.to/@nz_molecules/110530544890535383 comes the full, wordy #ChemEd blog, using whole sentences with greater explanation, more examples. It's here https://www.makingmolecules.com/blog/electrophilic-aromatic-substitution
A day late for my 200 level students ... but they knew it all anyway?

l collected resources and tools for making great #GraphicalAbstract - feel free to read/comment/share and stay tuned for part 2.

Here is the second #SciViz #ChemEd #Chemistry 1pager about electrophilic aromatic substitution. This one looks at activation & directing effects. If I'm honest, it has already been summarised (a summary of a summary) last week but it hopefully gives some useful information. Enjoy (or perhaps just be keep the previous one!)
#chemiverse

As promised, here is a more succinct #SciViz #ChemEd version of electrophilic aromatic substitution. Less explanation but all the information (& directing effects) ... hopefully.
Next week should see a bit more detail on activation/directing.
Hope these are useful #chemistry #chemiverse

Here is the first #Chemistry #ChemEd summary for a while (blame S1 teaching). It is electrophilic aromatic substitution. I'm out of practice & it is too cluttered. A minimal #SciViz version out later in the week. Hope it is useful.
Hopefully, I should be a little more regular at publishing these (once the marking is done)
#chemiverse

Oh! This looks like a fantastic workshop!

New blog www.makingmolecules.com/blog/asymhydroboration covering substrate & reagent controlled hydroboration. Also discusses allylic strain.
The #chemistry #SciViz #ChemEd 1-pager https://mas.to/@nz_molecules/110263410104435237 … was the infographic version (well, not the good. It was the version with minimal writing), this blog uses full sentences & has more detail (including full references for once).

It's been a while since I posted anything. Anyone currently working in a university will understand the fun if trying to do more with less.
This post was started in March after I did a #chemistry #SciViz #ChemEd 1 page summary on anti-Markovnikov addition. It is the stereoselective variant (covering the classic pinene reagents). Aimed at PG not UG.
I'll do a more detailed blog post next week & then get back to UG summaries.
I hope someone finds it useful. #Chemiverse

#PhysicsFactlet
At optical frequencies, most media respond to an electromagnetic wave proportionally to the electric (magnetic) field applied, and are thus said to be "linear".
In such media a monochromatic wave can be slowed down, resulting in refraction, but its frequency is unchanged.
But for all real media, the reaction to an electromagnetic field is only approximately linear, and for high fields it is possible to see deviation from linearity.
One consequence of a nonlinear response, is that the medium can generate frequencies that were not present in the pump wave, the simplest case being the "second harmonic generation" where a wave of twice the frequency of the pump is produced.
But, due to the time reversal symmetry of Maxwell equations, if we can generate a wave at twice the frequency, we can also take that and convert it back to the original frequency.
So, in order to maximise the amount of second harmonic generated, one needs to make sure that the phase of the pump and the second harmonic do not drift while the waves are propagating through the crystal. If these "phase matching conditions" are not satisfied, the energy will flow back from the second harmonic to the pump.
