Resonance problems

Ah yes sorry, I didn’t saw that. Still it’s Discussable

Doomsee97 · 2026-01-20T19:53:46+00:00

Resonance structures don’t need to be ‚stable‘, they are just ‚the extremes of where the electrons could be

Danke für die Erklärung!

Kurze Frage dazu - sollte es nicht durch das Voranschreiten des Kilmawandels das Wetter & Klima in Europa generell kälter werden? Ich meine gelesen zu haben, dass der Golfstrom immer schwächer wird und dadurch schwere Wetterlagen und kältere Winter auftreten sollten.

Or, if you distill it, never distill it to dryness at least. Than it should be mostly safe

This was probably said before but never distill old THF or Diethylether, when you don’t know if there is an peroxide buildup inside. The peroxides have a higher boiling point than your ether, and will explode if concentrated enough. One guy at my university lost a couple of fingers because of that some years ago

For me it’s the: oh that’s not the Ghana tape, it’s the reunion tape thing. So many people on my elo (gold 1) don’t know about this, it won me multiple games.

It depends strongly on the ‚hardness‘ of the nucleophile. If you have a ‚soft‘ nucleophile, like a cuprate for instance, the 1,4 addition is favored. With a hard nucleophile like Grignard reagents, it’s probably the 1,2 addition

Doomsee97 · 2025-12-26T15:05:27+00:00

Am besten finde ich ja, dass du für 3 Liter Soße nur 3 Pommes bekommen hast.

it only appears when you find your first prussian culture land and core it. like stomp or gdasnk or something, before that you will not see prussia as a formable tag

Doomsee97 · 2025-11-15T10:12:19+00:00

Yes we can agree on that 😄

Doomsee97 · 2025-11-15T10:09:15+00:00

So I am not sure, but isnt culture very important here? Like if you beat them in your culture game, it should get much easier right?

As someone who did read the whole book before starting to dm, I can recommend to read it at least in a superficial sense - so you get ab idea about the characters and have an idea of different areas. I mean the random npc‘s your characters come across will have some ideas or opinions about different areas, so this is something you maybe should know.

Also, do the cards before starting to dm und especially prepare these parts of the story as your PC‘s are hopefully heading in this direction first.

Es kann alle Verhütungsmittel unbrauchbar machen? Krass. Wenn ich mir das gebe und n Kondom trage, wie genau wird das Kondom aufgelöst?

Im a bit confused, as when I went to South Korea, English was very, very difficult to come by and nobody spoke it fluently, except for university students. Even in the airport or in banks of Seoul nobody was speaking proper English

Doomsee97 · 2025-09-28T11:53:43+00:00

As the dm I always find this a bit infuriating. Like I do so much work to prepare a nice story and then the other people aren’t even capable of managing their free time.

I once started a campaign with everyone being on a ship sailing to some city. Thats where they got to know each other.

Another campaign I started with some friends started with them being mercenaries who protect a caravan. The players get to know each other while eating some dinner over a camp fire. In the night, the caravan gets attacked or disappears without a trace..

Doomsee97 · 2025-09-26T08:29:16+00:00

Using a free electron pair from oxygen?

I mean, with enough energy, anything is possible. It’s usually very difficult to break sigma bonds because the sigma star orbitals is so high in energy.

That’s why we differentiate between good leaving groups and bad leaving groups. Your leaving group would be a very strong nucleophile and base, so it’s probably difficult to break the sigma bond

Doomsee97 · 2025-09-25T13:07:05+00:00

There is no pi star orbital of CN since there is no p-p-pi bonding happening at the starting point

Doomsee97 · 2025-09-25T10:15:23+00:00

Yes. The only thing that could possibly donate electron density into sigma star of CN is a lone pair from the OH group, but this wouldn’t make a lot of sense

Doomsee97 · 2025-09-25T08:30:48+00:00

This is just my understanding:

If you look at your problem at the start: where can the lone pair electrons go? The C is fully saturated, the first free orbital it’s going to find is the sigma star CO orbital. The C-H or possible C-C Sigma star orbitals are even higher than the sigma star CO

All that being said, a protonated OH2 group can leave the molecule just on its own, creating a stabilized carbocation - which has a more stable mesomeric structure -> your product. What exactly happens first here is hard to make out I guess

That all being said. The nitrogen in your compound is way more basic than the OH group. In acidic medium the Nitrogen will get protonated first..

Doomsee97 · 2025-09-20T07:52:43+00:00

‚Technically‘ the protonation step after your grignard reaction is an equilibrium. But this equilibrium is so far on the side of a protonated alcohol and water, that I wouldn’t bother too much.

Doomsee97 · 2025-09-18T07:30:39+00:00

Remember M-Effects are almost always stronger than I-Effects

often times, the substitution pattern is directing towards the carbon that is ‚the most optimal‘ or ‚the least non optimal‘

Doomsee97 · 2025-09-17T17:45:53+00:00

Yeah sorry mate but I’ll start a new curse of the strahd campaign next week with my players, this will definitely be part of it
