Consider the compounds 1-Bromo-2-(bromomethyl)butane and 2-Ethyl-1,3-propanediol As can be seen they are structurally similar compounds. The first has bromine substituents and the second has hydroxyl substituents. My question is why does one have a butane base chain whilst the other has a...

TL;DR Summary: E1 or E2? I did the E2 hoffman elimination because it's tbuOh so it's bulky hence does E2 with Hoffman as major product so I chose option A. But the solution manual has done E1 reaction and rearrangement so the answer marked is C. What is the correct mechanism?

This may already have been answered but I can’t find it. If organic matter is disturbed, exp. on the moon, does the matter experience a gravitational pull?

"My teacher had mentioned that resonance would occur here due to the presence of a positive charge if benzene is attached. However, if we consider two bonds without breaking them, there will be one pi bond. So, will there be no resonance due to it?"

I’m starting my PhD in Organic Chemistry this Fall. I want to review all of undergraduate Organic Chemistry and I’m trying to develop a plan of attack. I did alright in lectures but not perfectly and did quite well in labs. I don’t want to be bombarded in grad school and want to have a proper...

Summary: What’s the best way to review inorganic chem in preparation for OC. Assume zero recall on basic college chem. Are there study guides, online courses, etc. for this specific purpose?

The molecule is p-phenetidine

Are all non aromatic carbon chain aliphatic ?

We studied in chemistry that the concept of oxidation and reduction is the exchange of electrons between two chemical substance ,but when i started to study organic chemistry i saw that when we talk about for example the oxidation of a compound it can loss atoms and change his constitution...

A good candidate for the sample retrieval mission. https://www.nasa.gov/feature/jpl/nasa-s-perseverance-mars-rover-makes-surprising-discoveries

It is very important to recognize that, in general, the rules of the nomenclature of organic compounds are written in terms of classical valence bonding and do not imply electronic configurations of any kind. [Mentor Note -- Representative link added below]...

I think the correct ans should be c (i.e C>D>A>B ) but its given d in my textbook( There can be a error also but I'm sure) I think C should have the highest basic strength since Hybridisation of N in this is Sp3 so it has the least electronegativity so it can donate its lone pair easily Then it...

Summary:: Please see picture below The dotted line at Test 3 means to continue using the above solution, and add NaOH with the teat pipette. The dotted line separating tests 3 and 4 should be a hard line, which means to use a fresh sample of FA10 and perform the test. It is also known that...

Because you know, science. Nitrogen is nitrogen whether it comes from a factory or a bovine posterior, and ‘natural’ insectides can be every bit as toxic as ‘artificial’ ones not to mention reducing crop yields but people have weird purity taboos around food and organic is kosher/halal for...

Basically this would be a closed loop geothermal system for electrical power generation. The system would consist of 2 Horizontal Wells connected creating a U-shaped closed loop cycle using thermosiphon effect, with constant recirculation. It's not really a conventional geothermal power...

... with the intention of going into novel drug synthesis. It might be a bit of a reach to ask this on a physics forum, but I see chemists among us, so I guess this is as good as any. To those of you with experience in the field, what makes a good organic chemist? What makes a good medicinal...

For organic chemistry, what is important to memorize when I am reading a textbook? Should I memorize the structures and names of different organic compounds when they are described as examples? Or is it more important to memorize the organic reactions? Also, does anyone have any tips on how to...

Summary:: I'm always unable to find the products of a chemical reaction. No Matter how much concept I study I can't ever get products from reasoning. Here is the question: What is the major product of this reaction? . OPTIONS : MY ATTEMPT : First of all I can see that in...

I want to add some diluted dishwashing detergent to a bottle for spraying cockcoach, the bottle is claimed to degrade with organic solvent. Is dishwashing detergent organic?

when we transfer water vapours from steam generator isn't it like that the pressure of atmosphere around the organic mixture will increase so we have to boil the organic mixture more so as to make equal the pressure of atmosphere which is water vapour pressure + pressure of atmosphere is equal...

Hello All, I have attached my questions with pictures in attached photos. Look at screen shot 46 first then screen shot 47. I am having trouble ranking acidic protons. In my Organic book it has the order of: 1)Charge 2)Atom Type 3)Hybridization 4)Resonance 5)Induction Things I know: S is able...

Well I have two possible answers, it's either 1-(cyclopent - 1', 4'- dienyl) methyl ethan-1-ol or 1-methyl - 1 - (cyclopent-1',4'-dienyl) ethan-1-ol. Unfortunately the answer wasn't provided in the textbook.

I think that the double bond would be broken in some way but what happens to the two bromines? do they remain in the ring? (or does HBr forms? is it possible?)

I've attached an image from the book "nuclear physics" by John Lilley. It says "in only one case is the restulting photon energy sufficient to cause re-excitation". My question is what is this one case? I recall my lecturer saying only decay to S01 is sufficient to cause re-excitation, but I...

What does it mean and why do acetophenone and acetic acid have it in their name ?
