Looks like I forgot to share this one. The standard pedagogy for hydration of chloral is that the Cl atoms make the carbon more delta+. We were a bit surprised (initially) to find this isn’t the case. Sorry textbook authors!!!! pubs.acs.org/jceda8/artic...

Our fresh look at the inductive effect is out in J. Chem. Educ. This was a really satisfying collaborative effort, and I think you might be surprised by some of the implications. pubs.acs.org/doi/10.1021/...
pubs.acs.org
Rethinking the Nature and Extent of Inductive Effects in Organic Compounds
The inductive effect is generally taught as being transmitted through the σ-bond framework in organic molecules, diminishing with each bond. This historical position does not align with more recent studies, and we show that the inductive effect in neutral molecules is effectively limited to one bond. Evidence of onward transmission (e.g., 13C NMR chemical shifts) should be viewed with scepticism. In charged species, where an electron-donating functional group is coupled with a suitably disposed electron-withdrawing substituent, the effect is transmitted over more bonds. These examples should be considered as polarizability rather than ‘purely’ inductive. Examples that are commonly described as a through-space field effect are better explained by polarizability/orbital perturbation. This work presents a more complete view of the inductive effect and its interface with polarizability.

Soft magnetic hysteresis in a dysprosium amide–alkene complex up to 100 kelvin - Nature
A dysprosium amide–alkene complex shows soft magnetic hysteresis loops up to 100 kelvin, arising from the high charge density of the amide ligands and the structural role of the pendant alkene.

Someone does a PhD in a subject I don’t understand. They worked hard. That person is female. They probably worked harder and have barriers I don’t understand. But I also have a PhD. How the hell does it diminish me that they have the same qualification? Let’s just be kind to one another!

First post on here for #chemsky you’ve always been told that alkyl groups are inductively electron donating. I’m afraid that’s not actually true! There’s a fair bit of evidence that they are electron withdrawing and we’ve just added to that! pubs.rsc.org/en/content/a...
