I have this assignment, and from this chemical equation, CaCO3 + 2 CH3CO2H ----> CO2 gas + H2O + Ca + 2 CH3CO2 I have to name the products and I don't know what CH3CO2 is! Can you please help? THANKS!

Hi, i've read the other posts on the oxdiation of alcohols in wine and i find it very interesting, however contrary to his experiment im attempting to design and conduct an experiment whereby i find out the rate of oxidation of alcohol in beer. It is known that the oxidation of alcohol in beer (if i leave it exposed to air) is mainly due to the bacteria that is working on it. I do not know how long i should hold this experiment and the way about to do it. If i use some Potassium dichromate or potassium permaganate to instantly titrate it to completely oxidise the solution and backtitrate with hydrogen peroxide ( for permaganate) or potassium iodide and sodium thiosulfate …

cant ethers be prepared by clemmensen or wolf-kihsner reduction of esters if not then what is the problem:eek:

Why is isopropyl alcohol so widely sold and used rather than propyl alcohol? It would seem to me that the isomeric form would be more difficult to make, and therefore more costly. Or, is the common drug store stuff actually a mixture of the two? Of course, the ingredients listing would not reveal that. imp

What are criteria tha are usually used to judge whether a preparation method is good, besides yield and purity of the products? For instance,benzoic acid form hydrolysis of benzamide..etc..organic preparation.

I am really not familar with IUPAC? Does anyone have any idea what this compound might be? A benzene ring with a methyl group, a methoxy group and a O double bonded to an O.

So for the first reaction, I'm assuming that methylcyclohexane with Br2 (and light) will form 1-bromo-1-methylcyclohexane (because there's a tertiary hydrogen). Taking that through the 2nd rxn with yeild 1-ethoxide-1-bromocyclohexane (ethoxide=strong base in protic solvent) Hopefully I am right, i have no way to check the answer. I tried to search but could not find an answer and want to know if my logic is flawed or not. Also, is there going to be an E1 (minor) rxn after adding sodium ethoxide? or not? I appreciate anyones help.

I need help finding how molecules make an ester smell good after a condensation reaction. Can anybody help? Thank you in advance.

one thing that puzzles me lot is what actually changes plane of plane polarized light when it passes through optically active solution( i.e what sort of physical activity is going on there? which is the most optically active compound known

Hi all, I wish if I can find an experimentalist who can answer this question. I am physical chemist who would like to prepare sodium ethoxide from sodium and ethanol. my question is how to handle sodium (clean, prevent it from burning...etc) before I add it to ethanol? Thanks Hany

According to wiki benzene's health rating is 2 ("2. Intense or continued but not chronic exposure could cause temporary incapacitation or possible residual injury. (e.g., chloroform)") however for phenol the rating is 4 ("4. Very short exposure could cause death or major residual injury. (e.g., hydrogen cyanide)"). Is phenol really that dangerous? How feasible is it to work with it? Is it possible to inhale vapours and die or anything like that?

The benzoic acid is prepared by alkaline hydrolysis of benzamide I would like to ask why the shape of benzoic acid obtained is Needle-like and why there is yellow ppt. after boiling benzamide with NaOH for about 15 minutes? Thanks

Could someone please tell me what the basic functional groups are? I can only remember the one for Alkanes... Thanks

What are all the possible isomers of Propane?

I'm looking for ASTM D1652-04 to determine Epoxy equivalent weight (EEW) Pls help me!!!! Thanks

I'm looking at a question that is asking me to predict the 'relative stereochemistry' and 'draw the predicted structures' for cinnamic acid, cis-stillbene and trans-stillbene. My knowledge on stereochemistry is somewhat limited, as I just learned it this week. Could someone explain the solution to the problem for me please. I'm quite confused..

hello every body i want to synthesis pbo2 ok ..........now the eq say if i have lead oxide pbo how can transfer to lead diooxide para netroaniline .......how can i synthesis this

it seems totally sci fi but i was just wondering, is it phisically possible to mix animals through dna? i was thinking of if u could, transform the dna and then mix that with something like stem cells could you play god and create your own new creature? im guessing no but id like a scientific view to it all, and maybe if it was possible to even somehow mix say, a bat and a lizard to create a dragon-like creature (and i only mean physical looks like it would be the size of a baseball and would not breath fire, and maybe not even possess the ability to fly...)

'm doing my organic lab report and there are two questions I have no idea how to do. I've asked the prof. but he takes forever to email me back so...... The questions: Write equations showing how caffeine could be extracted from an organic solvent and subsequently isolated. Write equations showing how acetaminophen might be extracted from an organic solvent such as an ether, if it were soluble. how would you go about doing this??? would you use a simple reaction equation with reactants and then products? we used dicholormethane to extract the caffiene from tea so would you take the caffeine molecular structure + dichloromethane= the products??

Hi, benzene has a sandwich structure with delocalised pi electron over and under the carbon ring. Does this gives the stability to benzene because all the p-orbitals overlap to form a diffused ring of electrons. Or is it something else. Thnx

Hello I have a question for you all regarding incorporating an isotope into an alcohol. I just have to show the mechanism. I checked 2 textbooks and google but no help. T-butyl alcohol is treated with H218O and sulfuric acid. The end product looks just like the beginning, but now the t-butyl alcohol has a 18 in front of the O for the isotope. How do you think this was done? How should I draw it? __|__OH H218O | H2SO4 --> __|__18OH | Thank you for your time and help.

Never been good at this IUPAC naming business... I have a molecule which is a pyrrole ring with a linear alkyl chain attached to the nitrogen, containing 7 carbons with the last 2 sharing a double bond Best guess I've got is 1-(6-heptenyl)pyrrole... sound right?

How do you know which solvent to use to dissolve an inorganic solid choosing from ethyl acetate, hexane, and water?
