The Periodic Table

Hm, to post 311 words as a series of comments...

meh, life is short

@Mithoron ;P

I regret talking about books in general, it was sort of off-topic.

@orthocresol yeah, I too think we could have discussed it later, in a separate meta post

There's also an argument of who cares, it hardly seems like anybody is buying these books

12:55 AM

@pentavalentcarbon I see where you're coming from and I think I made an implicit assumption that a book would be more like a reference work, which was maybe a bit influenced by my own reading patterns. With something like a coffee table book, though, my concern is still the target audience. You would be marketing to... casual readers of specialised information (hardcore readers will go for the textbooks, laymen will go for popular science).

I'm not saying such a group of people doesn't exist, but it just strikes me as weird, because I would have thought that the Internet was the natural medium for that, not a book.

Anyway, it's a rather tangential discussion, which is why I don't really want to respond in the comment section. And if we agree that it probably won't work then it's sorta moot anyway

@orthocresol I already covered that argument in my post. we needn't care about who buys the books, it's the publisher's worry

It's fine if you don't really want to debate this, I'm not particularly keen on it. I don't think there's a right or wrong answer either.

flags comment chain as primarily opinion-based

@GaurangTandon well, I care, if people are reading this book and getting negative impressions of the site

I obviously don't care about the sales numbers. I don't think George Duckett does either, given that his "cost" of publishing the book is zilch.

I mean... actually visiting the site also exposes one to the good and the bad. I get that point.

oh well

not really keen on talking about this now I've spent 13 hours in the lab today

wow, my answer got long really quick o.O

Which one?

meta answer

@Abcd you've a lot of unaccepted old questions on both the main and meta; just a nice reminder that you may wish to accept answers to a few of them :)

There used to be a place on the internet where you could enter compounds and things such as acidity constants were calculated, including which proton deprotonated in which order. Alas, I can’t find the site any more. — Jan Nov 21 '17 at 14:31

@orthocresol do you know what website Jan is referring to?

A: Why does a mixture of nitrous acid with concentrated nitric acid cause nitration of benzene instead of nitrosation?

4:11 AM

You were absolutely correct when you said that nitrosation takes place. What actually happens is that after nitrosation occurs, concentrated $\ce{HNO3}$ oxidises the nitroso group to form nitrobenzene. Source A Guidebook To Mechanism In Organic Chemistry; Chapter 6, section 6.2;Peter Sykes

A: NGP mechanism vs the simple carbocation mechanism

From Clayden (Chapter 37 Rearrangements page 976): Intramolecular reactions (including participation of a neighbouring group) that give three-, five-, or six-membered rings are usually faster than intermolecular reactions. It also gives the exact same example as your question: ...

@GaurangTandon There are not many people conversing on earth science chat. Maybe, the question has more chance of being answered here due to more traffic.

Q: chemistry text book not containing electrophilic aromatic substitution

11:09 AM

-1

I dare you to find an advanced chemistry textbook that does not contain the topic electrophilic aromatic substitution. Have you found it? name the title.

@GaurangTandon I havent got convincing answer for some ... Most are accepted though

@Abcd did electrophilic aromatic substitution kill a friend of this guy?

@AvnishKabaj also the one about CIP rules digraph that I noticed a day before, and another question on meta post about migration

@Abcd alright, was just a friendly nudge

@ApoorvPotnis hmm right

@GaurangTandon man those are your questions not Abcd

@AvnishKabaj excuse my mistake, thanks :-O

Though I'm still not comfortable with that NGP question, so I'll leave it open. Please don't mind, I may come back later to detail in your answer itself, but I don't have the time right now

A: Understanding the CIP configuration for cyclic substituents with hetero-oxygen atoms

Sure

@Abcd

CIP rules for cyclic substituents are different. See this question for the rules. (The rules are given in the question itself). This will be the hierarchical digraph for the right side of the molecule. The atoms encircled are the ghost atoms. From the digraph one can see why the compound is...

A: Prins reaction mechanism

Your generation of electrophile is correct the subsequent primary carbocation formation by the attack of electrophile is incorrect. In my second step, that particular carbocation is formed since $\ce{Ph}$ is an electron-withdrawing group. The benzene ring stabilizes the carbocation th...

@Abcd Good to see that you have a good memory

But you didn't accept anything

@AvnishKabaj Oh really?

@AvnishKabaj Agh I now realise this was such a noob question on my part

Anyway ... being noob = part of learning process.

Q: Gibbs Free Energy calculator

5:25 PM

Are there any computer programs or online resources that could help me figure out whether the reaction will take place or not, and if yes, at what temperature?

I dont think a calculator is even needed for basic arithmetic of G = H - TS

@GaurangTandon, just a heads up that that RE60K guy was highly disruptive/rude/antagonistic when he was still active. He got suspended for a very long period of time and doesn't seem to want to ever come back (just as well). Not that you did anything wrong, but just something that may/may not influence your actions on his posts/comments...

@Martin-マーチン Thanks. This community has become crazy. This year whenever I asked anything, my question was downvoted or even closed. And I can see many good questions (asked by other users) downvoted. This community is no longer like what it was a few years back. A few years ago no one downvoted my question and my questions were never closed. This year, even my old questions were downvoted by some people. I can see some crazy people, and even administrators who know nothing about chemistry, have come and taken power. I'm ready to close this account since the platform is no longer friendly. — Alright 8 hours ago

10:14 PM

Well, it's true, we now downvote and close much more...

Probably what happened is as the rate of bad questions appearing has increased over the past few years, some of the negativity has carried over. On the other hand I don't see any of their questions closed, and most people don't understand what a downvote actually means.
