Wordle Unlimited: A New Twist on a Classic Game
Wordle Unlimited takes the beloved word-guessing game we all know and love and elevates it to a new level of excitement and engagement. Created as an extension of the original Wordle, this version offers players endless opportunities to challenge their vocabulary and problem-solving skills without the constraints of a daily limit.
At its core, Wordle Unlimited maintains the same simple yet addictive gameplay—a player has six attempts to guess a hidden five-letter word. With color-coded hints that indicate correctly placed letters and those present in the word but not in the right spot, players are encouraged to strategize and deduce their way to the correct answer. However, what sets Wordle Unlimited apart is its feature of infinite play. Whether you are a casual player looking for a quick game during a break or a dedicated word aficionado seeking to sharpen your skills, this version offers a practically limitless supply of words to guess.
Additionally, Wordle Unlimited fosters a community spirit among players. Users can share their scores and engage in friendly competition, challenging friends and family to beat their best times. The game’s interface is user-friendly, making it accessible for players of all ages.
What’s more, Wordle Unlimited frequently updates its word list, incorporating new terms and phrases, which keeps the gameplay fresh and engaging. With customizable options for both word difficulties and themes, players can tailor their experience to suit their preferences.
In essence, Wordle Unlimited is not just a game; it’s an opportunity to unleash your creativity, expand your vocabulary, and enjoy endless fun. Whether you’re playing solo or with friends, this game is sure to keep you entertained for hours on end!

While using HCl I received mostly monobrominated product, some significant part of substrate and little trace of something more unpolar (dibromo derivative?)

You mean monochloriated product, do you?

Which Carbonyl reactant do you use.

Organic Chemistry Forum / A-chlorination carbonyls with H2O2/HCl
« Last post by Parathormon on Today at 05:34:07 AM »
Hello everyone,

I have some question regarding to aforementioned reaction - as of my experience procedure copy from HBr/H2O2 where man use 1eq carbonyl, 1.1eq HBr and 1.4eq H2O2 but using HCl instead do not lead to full conversion.


As of my TLC for such procedure using HBr I received 100% conversion and selectivity to monobrominated product.

While using HCl I received mostly monobrominated product, some significant part of substrate and little trace of something more unpolar (dibromo derivative?)



As of my literature research it can happen due to slow reaction between h2o2 and HCl and even below 30% conc of hcl chlorine is not appearing at all, instead of this HCl is slowly decomposing H2O2 to oxygen and water.


Question to You - is it possible to somehow challenge this problem and use this procedure or it is rather not recommended? I also didnt find any work or patent on such reaction (monochlorination of carbonyls by h2o2/hcl).

Let's say I want to scale-up a reaction rom lab scale to pilot scale, there are defined parameters (Re, P/V etc) to get the RPM and power. Now my doubt is, How do I choose type of agitator, and how should I compare between different type of agitator?

Try contacting Elutia.  They make a TEA (Thermal Energy Analyzer) instrument. We used it to test for n- nitrosamines.  It first came out under Thermo, but I think Ellutia bought it from them.  The idea of the analyzer was to take the substances routed from a GC, pyrolyze them as they came out, then they were run through a could trap ( ours used EtOH and dry ice) and the left over gas went to the instrument.  The Instrument took the gasses (NOx) and reacted it with O3( O2 came in and was exposed to an electric arc to make ozone).  This chemoluminesced to produce red light which was measured.  There were other steps, but you get the.idea.  They might be able to help you.

Are you sure it is related to the OP question?

Can't think of anything that can be done.

Reaction speed basically depends of concentrations (or pressure) and temperature - if you keep these constant, reaction speed doesn't change.

You can speed up the reaction with catalyst or slow it down with an inhibitor - but that requires adding something to the mix (changing container material won't change much, as this particular reaction takes place in the bulk).

Sometimes it is possible to speed up the reaction with ionizing radiation (UV and dental cement for example), but that's opposite of what you need.

I can't change pressure or composition. I have only physical means.
I can play with the container where the gas is in. Modify its material.

What is the purpose  to do so.
I think you can only decrease pressure or rise temperature.
Also removing oxygen will shift to NO.

Hello
This is quite basic but I'm not an expert in chemistry...
2NO +O2 -> 2NO2
I need to slow down this reaction as much as possible, but the concentration of NO and O2 is fixed, and so is temperature and pressure. I can't add other chemicals...
Is there anything else that can be done e.g. applying electric voltage, magnetic fields, use the force...?
Thanks!
