Organic Chemistry

Hi all, I fell behind at Uni due to a bereavement and I caught up with Inorganic and Physical Chemistry but Organic I am struggling very much... I have to predict the major product of the attached... I believe it is using Cram's rule but I just do not get it! Any help is greatly appreciated

Hi everyone An exercise that's driving me nuts. Completely nuts. The question: Which products are being formed when but-1,3-diene undergoes 1 addition reaction? The correct answer: R-but-3-ene-2-ol S-but-3-ene-2-ol But-2-ene-1-ol Another possible answer would be: But-2-ene-1-ol But-3-ene-1-ol However, this answer is incorrect. Why is but-3-ene-1-ol incorrect? I've already thought of Zaitsev's rule, but that one won't apply to addition reactions. Can someone please help me? Thanks. Function

Hello everyone Reaction of this molecule With sulfuric acid and water gives us the following molecule. Main question: why not this molecule? I understand that OH binds to the 3rd, and also why not to the 4th molecule (Markovnikov's rule, if I'm not mistaken; correct me if I'm not right). But not why a methyl-group is being replaced by a H-atom on the single-bonded O-atom of the ester, leaving a carbonic acid. Is it because H2O leaves another electrophile H+-atom when dissociating in H and OH, and that perhaps a bond with H would be more stable than a bond with CH3? Secondary question: what's the name of the reacting molecule? I can think of nothing bet…

How much kj mol-1 needed to brake bond between two Carbons in Heptane?

I dont understand. Cells require exothermic, free energy reactions to function. The energy released by bond breakage (i.e. heat) in a cell does not contribute to the energy transfer in chemical processes, however the lower stability of the product and "good leaving group" (i.e. phosphate group) provide the energy for the chemical process (reaction --> product) to take place. But then what "energy" drives mechanical movement of proteins, and pumps, etc. if the "energy" is just either a chemical bond with a high potential energy (i.e. ATP) or a product with a higher stability (resonance of pyruvate at the end of the glycolytic pathway)? -I guess wha…

Hi guys, So I've been googling around and cant seem to find one bit of info I need. I'm hoping someone here can point me in the right direction to find my answer. I need to know the resonance form of 1e-1-methoxyprop-1-ene and I can't seem to find it anywhere... Any help is appreciated!

why is that chemical shift of no 1 carbon (NH2 group) is greater than no 2 carbon (NO2 group)...and no 3 carbon greater than no 4 carbon....what are the reasons.... thank you....

The compound Ch3-CO-Ch2-CO-Ch3 gives a positive iodoform test where the carbon involved in formation of iodoform comes from the active methylene group. This is well explained and justified supported by a mechanism. What intrigues me though is that the compound Ch3-CO-Ch2-CO-OEt does not give a positive iodoform test. The reason being that ( according to the book), OEt is better leaving group than -CI3 and thus instead of CI3 anion being relased the ethoxide ion is removed. But then, shouldn't the ethoxide ion participate in further haloform reaction. Ethanol can after all give iodoform test and once we have ethoxide ion in the solution, why doesn't it leads to the fomatio…

Hi all, I'm trying to make sense of this...why would molecules prefer to be at a lower energy state (more stable) if the universe prefers to be at a state of disorder? Thanks

If I ingested a bunch of cellulase and started eating grass, leaves, etc. wouldn't that be sufficient to breakdown the cellulose into digestible carbohydrates for energy?..just curious ~EE

I have been able to synthesize some compounds (which i believe are Schiff bases) using vanillin and the isomers of toluidine via three different methods,with a change in solvent and reaction conditions. while two methods gave crystals, the other gave an oily product. i am wondering why this happened. Could it be because of the change in solvent and reaction conditions? Also, what other method can i use in purifying the oil apart from column chromatography? thanks -umofiae

I want to measure the different chemical aspects in both GMO and non GMO fruits. What are the chemical aspects that I could measure in corn that would differ from GMO to Non-GMO?

I'm trying to find at least 3 constitutional isomers for CH3NO2 but I'm having trouble. Can someone help me come up with some isomers?

Hi, I am interested in making a molecule. Kindly see attached file. Please help me in figuring out reactions which are required to get this product. Thanks in advance

Hi, I would like to ask help and seek the expertise of professional chemists regarding nitrocellulose. 1) Can any grades of nitrocellulose (with varying nitrogen content/ degree of nitration) be used as a secondary explosive/detonator? If not, what is the threshold limit/concentration of the nitrocellulose grades considered as secondary explosives? 2) For nitrocellulose damped with solvent (water or alcohol), literatures specified that the damping agent/solvent phelgmatizes or deactivates the hazardous properties of nitrocellulose. In what does the solvent deactivates such hazardous properties? What is the underlying mechanism for this? 3) In what way does the degree…

Hi, i need help to synthesize sodium ethyl sulfate, which i plan to use to make nitroethane which i plan to use as substitude for diesel in ANFO. I just want to compare results of ANFO made with diesel and ANFO made with nitroethane... So i have googled procedure which i think is rly good just need some adjusting. I will copy full procedure and elaborate my thoughts about it, what i need is advice from someone experienced in this so i dont end up with diethyl sulfate which is toxic (only reason why i didnt already conducted few experiments on my own and find out correct way to sodium ethyl sulfate) Procedure. In 500 ml RB Flask was added 100 ml EtOH (97% is high e…

Hi, I just developped an android app in organic chemistry that can help students. And I'd like to have your opinion about this app, if you find it usefull, if everything works well on your phone, otherwise what problem you have. New reactions will be added later, but for the moment, I prefer to know if you like my app. Here the link in Google Play. Thanks

Teflon(polytetrafluoroethene) is an organic material for non-sticky pan coating. As we know, Teflon is a material with very low coefficient of friction. So during the production, how do producers coat such a low-friction material on metal? Why does Teflon have so low coefficient of friction in terms of its structure? Please help! Thank you so much!

As the reaction shown in the figure. I understand that acetals are quite stable unless in an acidic solution, so this reaction looks very strange to me. I cannot think of any other acetal reactions beside acidic hydrolysis...

So first off I'm new here! My name's Jordan. I'm looking for a forum to help me in my quest to get to know as much chemistry as I can and to get help for projects I wish to do from people who know what they're talking about. So anyway here's my question: So recently I have successfully synthesized Serotonin! With this success I thought it might be fun to make some other neurotransmitters. Right now Dopamine is my next product, which shouldn't be to hard to do. I think I got the idea on how to do that. Just a Decarboxylation of L-DOPA and that should be very easy. But then I realized that with the Dopamine I could also use it to make Norepinephrine. I'm still a very nooby…

I've been trying to make crystallized sodium acetate to make acetic acid (to then make banana oil). I mix vinegar and sodium bicarbonate and then try to boil off the water, however I keep burning the sodium acetate. Is there any wasy i can remove the sodiuma acetate w/o destroying it? ~ee

I want to make phenol from salicylic acid. I was hopping that I could decompose it with heat and collect phenol. Could anyone please give a procedure. I don't have any ground glass but I have test tubes, flasks, beakers and a distillation apparatus.

Describe an experimental setup to visualize the SN1 and SN2 reaction between n-butylbromide, secondary-butyl bromide and Tertiary butyl bromide.

Something I've never understood in chemistry is why don't salts (i.e. NaCl, NaBr) react with carbonyl or alkyl halides? -In theory, the Na and Cl dissociate in solution. The carbonyl or alkyl halide is added, and the negative anion (Cl, Br, etc) reacts with the positively influenced carbon atom...but this doesnt happen. Should a catalyst be present, or does theire need to be an immense amount of heat/ energy for the reaction to take place? ~ee

From my reading various places online it seems that plastic recycling would benefit from a cheap and easy method for identifying different plastics. Resin codes can be used but they are definitely not easy. They require someone to search around on the product to find them. That takes a lot of labor especially sense the codes are in many different places and some times very small. Some products don't have any codes on them at all. An easier way to identify plastic is to use specially made IR-FT spectrometers, but they are definitely not cheap. This limits there use and decrease the economic viability of recycling. Basically it seems to me like right now only municipa…
