You are right: it seems to spread like the plague. I agree that reaction is pointless and I think that it should be removed and blacklisted till the end of days.* At least ;-) (*Editorial remark: If you agree with the proposal please upvote this answer.) Currently, there are 93 questions with reaction and reaction-mechanism. Here, reaction can be removed ...

How to find out if a tag is good to have/make I present to you, the MAR Tag Test™ (abbreviated as MATT), a short test with three possible responses to each question, designed as a crude way of diagnosing the health of a (imaginary) tag. Imagine X, a tag$\,\ldots$ 1: Ignore spam. Some people used to tag stuff as beginner or subjective to prevent their ...

I agree that there are a lot of questions related to JEE on this site (I myself asked a lot of them!). However, I disagree that we should create a specific tag for them. Tags that don't describe the actual content of the question are called meta tags. Meta tags are discouraged on StackExchange for a very long time now, see this blog post from 2010. Examples ...

First of all let me state, that I really dislike the word "burninate". Especially for this situation, where you seem to have a just cause. Secondly, I am very, very strongly against deleting the tag. I was once under the impression, that the tag is essentially the same as the nomenclature tag. The usage explicitly states that the tag shall not be ...

tl;dr *sigh* It's not just done with renaming. Introduction Nucular is one horrible tag. For the reason you mentioned and for a couple more, well, mainly inconsistency. (And MATT is -2, in words: minus two.) Defined scope Let us just start with the basics, the scope definition. There is no tag wiki for this tag … yet! Who would have thought... well, ...

You're a bit too fast asking this question. The tag has not been alive for much more than three hours, and I would have caught it in one of my checks eventually. It is now a relic of the past, as I removed it immediately. My reasons are essentially that in which ever way you look at it, it becomes a meta tag, or it would indicate that the question is more ...

TRE notes and tips Don't edit closed questions! (This is covered with my query, but just in case) The rationale, if you ask, is an SE slogan saying "$\color{red}{\mathcal{don't~polish~turds}}$". Enough said I guess. Don't edit questions that you voted to close/flagged for closure. For the same reason I stated above. Please make substantial edits. Think of ...

TL;DR Yes, we do. TL;DR++ I think this functional group warrants a new tag, hence I would vote for keeping it. Usually I am a bit more hesitant creating new tags, but in this case I am sure there is no problem. Quoting quite liberally from Differences between phenols and alcohols: There is a fundamental difference between the two functional groups. ...

It's quite a meta tag... I'm not sure whether this is a great idea. The biggest trouble I have is that quite a few of these questions would probably be off-topic. For example, the check-my-work / amirite questions are not really well fitted for our format. Code (like actual program code) for debugging should probably better go to Stack Overflow, Code ...

We need to keep x-ray-diffraction. The most common application of x-ray diffraction methods is crystallography, however. However, there are other x-ray diffraction techniques used in the characterization of surfaces and materials, including: Wide-angle x-ray scattering (WAXS) - used to determine the degree of crystallinity of a (usually polymeric) sample ...

I think that creating some more tags for certain functional groups can actually be beneficial. Here are a few comments on the status quo and some recommendations: $\Large\color{\green}{\checkmark\small\text{(Completed.)}}$ Note that halocarbons is already a synonym of halides. $\Large\color{\green}{\checkmark\small\text{(Completed.)}}$ The tag ...

Let's burn breaking-bad. Some things are okay-ish to do when we're a small community, not so okay-ish when our community grows bigger. Now that we're in the bigger phase, we should be consistent with a lot of what we do. IMO burninating breaking-bad is a must. Let me (AKA the rest of the community) know whether you'd like an alternative tag instead in the ...

I would like to see it gone. There was a time, where we were still struggling with the scope of the site and where the community was small and where we were not sure in which way we would like to steer the ship. At that time it was useful to tackle the "homework" questions in a way that they do create bias. I'm quoting a very old stance of Manish: ...

It should be fine to reuse a tag wiki across sites (customized as needed to accommodate the subject). All user-contributed content is licensed under a Creative Commons license for reuse… but that license also requires proper attribution. But as a pragmatic matter, there a point where text becomes purely instructional, and it's not always practical to ...

The IUPAC is the International Union of Pure and Applied Chemistry does more than work to standardize the symbols and nomenclature of chemistry, although this is the work they are most famous for. They are also responsible for international efforts to promote chemistry, such as the International Year of Chemistry. Additionally, they disseminate knowledge ...

Based on uniformly positive early feedback, I went ahead and retagged all of the relevant questions, editing further where warranted.

We should let it die after a rewrite of the homework policy As is, I think the biggest problem with deleting homework is our mediocre homework policy that somehow asks for some kind of a bookkeeping tool of what is homework, what isn’t, what is allowed homework and what should be nuked from orbit. I have previously given my input of when I consider ...

Proposal of a different tagging system Functional group tags need not be scrapped entirely, but their usage should be restricted. Questions about the properties of functional groups may be tagged as such. For example, a question about comparing the C–Cl bond lengths in chloromethane vs. chlorobenzene may be tagged as hybridisation + halides. A question ...

It's not a bug. I don't know how the system determines what suggestions to show there, but it is completely different for me (logged in/out, different devices). It almost seems to be random. [...] it's been deprecated for a long time [...] Let's not forget, the homework tag is deprecated as a result of our meta discussions. The system itself doesn't ...

I suggest you tag it symmetry, and let us retag it group-theory (math sounds a bit vague to me).

The tag was on the question "Photoisomerization of Azobenzene", see the edit history here. I am responsible for making this tag an orphan, meaning as soon as I saw it, I substituted it to the proper tag. I do things like this at least once a week and I outlined the procedure somewhere on meta before. Unused, they are called orphaned, tags will be removed ...

Should we or should we not allow (and answer questions) that ask how to acquire a certain chemical? No, we should neither allow, nor answer questions about how to acquire a specific chemical.* But why? With any question we are adding to our scope. We always should ask ourselves, how helpful is it in the (1) immediate, (2) intermediate, and (3) long time to ...

Well, there are various things and taking care of as many of them as possible would be beneficial. Adding tags to one-taggers - there's lots of them. About 150 only in inorganic chemistry. Taking care of functional groups, nuclear and other (re)tagging stuff. Improving titles - removing mathjax, buzzwords for starters, but also making them as appropriate ...

I've thought quite a bit about the distinction between the different sub-disciplines, but this post and the linked one have revealed to me that I don't usually make a distinction between theoretical and quantum chemistry since I'm biased by doing almost entirely electronic structure. I almost never use "quantum chemistry" but "theoretical chemistry", and don'...

Considering it’s been around for so long and it has only three questions, I think removal is a safe option.

Indeed, ft-ir has been applied to questions that are about infrared spectroscopy. That still is - in my opinion - no reason to remove the spectroscopy. In general we don't remove broad tags just because there are more specialised versions; that may be a discussion for another time. I suggest to rename the tag. First I thought ir, analogous to the current ...

I would actually argue against combining the two, at least from a technical perspective. The chemistries of the lanthanides and the actinides are very different. Lanthanides mostly form only trivalent ions (cerium, europium, terbium, and I think a couple others being exceptions) with nearly identical chemical properties. The big differences arise in the ...
