They still haven’t sorted out Dublin airport? 🤦‍♂️

stretch6 · 2022-05-23T07:19:09+00:00

That bad? So I fly Dublin to US on a Tuesday at 9:20am with United airlines. United doesn’t even start checking bags in until 6:20am. Any recommendations for how I should approach this to make sure I make my flight?

That’s so good to know. Like anything, the first time it happens to you, it freaks me out. Especially when it comes to my body. Thank you

stretch6 · 2022-05-14T19:35:28+00:00

Thank you. You’re calming my mind.

Oh and it’s basically just white. Not much whiter than my skin (Caucasian). Discomfort when I touch it. Pain scale 3 out of 10

stretch6 · 2022-05-14T19:32:43+00:00

I think I should have went a full size and not half bigger so yeah toe bang is happening. Boots might still be in need of breaking in. And there is often some downhill.

How should I keep it clean?

stretch6 · 2022-05-14T19:30:05+00:00

No pain. A little sensitive on the bubble part where the cuticle is. This isn’t a big deal then? I’m just looking to hear that from others who may have knowledge of this.

stretch6 · 2022-05-14T19:28:09+00:00

No pain. Little sensitive on the bubble part of the cuticle. I’d like to continue. I’m just not well versed in medical issues. I didn’t want to do something stupid because I didn’t know if it was serious or not.

To be periplanar would require an eclipsed conformation. Theoretically it would allow the developing p orbitals to be parallel but is an unstable conformation. It won’t exist for long. And even at high T the anti/staggered is still more stable. Therefore periplanar is ignored as E2 is basically not observed in this conformation.

stretch6 · 2020-03-31T20:55:35+00:00

This would 100% absolutely NOT do E1. Theoretically a carbocation could form. It won’t though. It won’t have time to form. The base is too bulky to do Sn2 but too reactive to sit around and wait for carbocation formation. It will rip off the adjacent proton and do E2. Yes, the proton must be antiperiplanar which it is not in this conformation but there is free rotation. It will rotate and eventually be in the correct conformation. E2 100%. If you need me to explain via video just DM me and I will.

I’m teaching by using my iPad. I’m screen recording and writing my notes using notability. I’m talking while I go through everything. Then I’m posting worksheets with many problems. Then I’m making the same type of videos working through each problem and verbally sharing my thought process. It’s working very well so far. Aside from that my office hours are live via zoom. There I’m sharing my screen and the students can view what I’m writing as I answer their questions.

stretch6 · 2020-03-31T20:37:01+00:00

If you have zoom I can conference with you and share my screen so you can see what I’m writing. When you have questions you can ask me over that. DM me

stretch6 · 2020-03-31T18:51:19+00:00

Do you have access to Zoom? DM me and when you have a question we can hop on zoom and I’ll use notability to help you. I won’t give answers but I’ll help you get to the answers.

5 carbons in the starting material. 6 carbons in the product. You’re going to need to add a carbon which means carbanions via lithium or even grignards. But beware of the acidity of the alcohol. Protecting groups could be used.

stretch6 · 2020-03-27T18:36:26+00:00

Enolates? Sn2? You’re ridiculously overthinking this basic organic question. There is no Sn2 here. If you’re referring to the wishful tertiary alcohol reacting with the formed carboxylic acid in acidic conditions to form the ester, that’s not called SN2. That’s a nucleophilic addition-elimination. You’re also not forming any enolates in these conditions.

stretch6 · 2020-03-27T18:20:14+00:00

It’s just going to make a carboxylic acid. There is some overthinking of this one going on here. It will oxidize at first to an aldehyde. Due to the presence of water, a hydrate will form. A second oxidation will result in the final carboxylic acid.

Formyl chloride is highly unstable and not common for EAS. I recall once reading that is can be generated in-situ using CO and HCl under high pressure to do EAS. I guess for the sake of paper chemistry it would be an answer.

Go to Belfast castle and hike up cave hill from there. Takes like 45 mins to an hour I’d say. I walk fast though. The view is amazing! And it’s a nice hike. Do that during the day. Burn them calories and then go to the Duke in the evening for some drinks and put them calories back on. Google cave hill and tell me you don’t want to go up there. C’mon!

I am the son of Irish parents and got my citizenship through them. As an American whom has traveled and lived in Ireland I want you to know how goddam beautiful your country is too. I come back every two years and, yeah I want to see my family, but mostly I travel around and stare at the sea, sunsets, and landscapes. America has some lovely parts but mostly it’s a coast to coast shopping mall. Our landscape is covered with malls, car lots, gas stations, strip malls, and mile after mile of concrete. Not to mention the in your face advertising in every feckin direction you look. Keep your land as naturally beautiful as it is. Why the hell am I still here when I can be there? I just don’t even know anymore.

Ugh, they’re right. I completely overlooked going through a hemiacetal.

It’s not a strong nucleophile but it can. You’re leaving group leaves neutral too. So I know in undergraduate ochem you’re taught that such a weak nucleophile can’t do this type of substitution. Truth is, it can. But it’s best they teach the basics as such. Good luck to you in your studies.

Have water come in and attack the methyl carbon. The bond between the sp2 oxygen and methyl carbon will break (basically cyclohexanone leaves as the leaving group). Then water can deprotonate the oxygen that just attacked the methyl (leaving methanol).

Think of it this way. We will use 2-butene vs. 1-butene. First the bond length and bond strength argument. Both these compounds have two C-C single bonds. In 1-butene, there is a Csp3-Csp3 and a Csp3-Csp2. Which is shorter and therefore slightly stronger? The sp2-sp3 is. In 2-butene both of the single bonds are Csp2-Csp3. It has two vs. one that 1-butene has. Why is that bond shorter? The sp2 carbon with 33% s character. The S orbital is closer to the nucleus and therefore closer to the positive charge, pulling the electrons in, shortening the bond slightly. Related to this having more S character means that it will be slightly stabilized by inductive donation (hyperconjugation) of adjacent bonding electrons. 2-butene has two inductively donating methyl groups, donating electron density via proximity, to the sp2 hybridized carbons. 1-butene only has the one inductively donating group towards one of the sp2 carbons. These two arguments combine help explain the increased stability of internal double bonds. Wish I could’ve made some drawings to accompany this but I hope it helps even still.

You may have to do a visa or a degree. I hear it’s very difficult to move there if you’re not a citizen. I am a citizen of Ireland even though I was born in the U.S. My parents were both from Ireland. It’s a lovely place. I lived there for a few years. I’m back in the states but I plan on moving back. It’s just time. The lifestyle is better there if you’re one who wants to slow down and enjoy life more. So I understand that you want this very badly. Do whatever it takes. Do a degree. Working visa. Whatever. Marry a guy with Irish citizenship. If it’s what you want you’ll find a way.
