I need help coming up with the synthesis of the molecule attached below. I keep trying it, but I cant get it to work out, do you guys have any tips suggestions on how to solve this. All of the carbon atoms come from alcohols that contain 4 carbons or less, that includes any bromides, grignards, wittig reagents etc. thanks

The question is regarding the electron transport chain within the mitochondria, specifically how the electrons transport protons through the first and third complex. The basis of this question can be found at the tutorial at ... http://www.johnkyrk....tochondrion.swf As each pair of electrons passes through each individual complex, they cause the transport of two protons across that complex from the matrix to the outer chamber. The electrons move by passing from the NADH/FADH2, to the flavin inside the complex (FMN) and then "bouncing" between the iron cores of Heme molecules (porphyrin rings) also within the complex. In the process of jumping between the…

Simple question, the gas chromatography graph shows two curves to show the ratio of two products. Will the retention time for each product always be in the same order for the two products? I am asking because we pooled class data, and although the ratios are the relatively the same, the order of retention time was different. For instance: Data 1: 1.04min 40% 1.06min 60% Data 2: 1.04min 60% 1.06min 40% Can anyone explain? Thanks.

I was just wondering if it would be a good idea to autoclave a bottle of ether; I need it sterile for a Virology experiment. Would it work or would the autoclave cause the ether to evaporate since it is volatile? I need to know soon because I don't want to autoclave the bottle of ether only to come back and find that it all evaporated; of course I could just have the lid on tightly to prevent evaporation. Can someone give me advice on how I should proceed?

Can anyone tell me other chiral forms/optical isomers of methylphenidate (Ritalin), and there effects as to the drug it's self?

Hello everybody! I am trying to solve an assignment. I have a polychlorinated decane mixture. I have been asked to come up with any way (chemical derivatization or chromatography) to distinguish the following compounds in the mixture: 1) compounds containing vicinal chlorine 2) compounds having geminal chlorine 3) Compounds having terminal chlorine I will aprreciate your help in this connection. Any literature references would be helpful regards, didni

I am not a student, but am a hobbiest of most all sciences. I would like to know if it would be plausable to put poly base materials into a deoxygenated, compression chamber to recreate hydrogen sulfide? I realize that polymers have an unstable atomic weight and am curious if this would cause an unstable atmosphere during the process.

Hello, Can any one please help propose a chemical structure for a compound with the nmr data in the link below (CNMR, DEPT 90, DEPT 135, HNMR, HSQC). Acetone was the solvent used for the nmr analysis. http://img829.yfrog.com/gal.php?g=ha9.jpg Any suggestions will be highly appreciated. Thank you.

how would one go about extracting citric acid from lemon juice, would distillation or Electrolysis work?

Quick question: I'm looking to get dopamine and serotonin tattoos. I just want to make sure these images are accurate. Dopamine: is there a difference between OH and HO? (i would prefer to have OH, as to avoid a Christmas tone.... "HO, HO, HO") Serotonin: does the NH have to be: N H (vertical) or can it stay "NH" (horizontal) Thanks for all your help

Three solid forms of glucose are anhydrous alpha, alpha hydrate, and anhydrous beta. Assume at equilibrium at 23, the solution is 50 wt% total glucose with beta:alpha = 5:3 Note that alpha hydrate is 10/11 glucose, e.g., 11 g hydrate corresponds to 10 g anhydrous. Exactly 1100 g alpha hydrate is mixed with water. @ equilibrium, there is 160g aqueous solution plus solids. What is the mass of each solid phase? The answer is supposed to be 22 g of alpha glucose hydrate. But how do you get that? I figured out that the whole system has 100g glucose on anhydrous basis and 30g of alpha and 80g of beta (80g of total glucose) in solution. But where does the…

In Organic Chemistry class, we did nitration of sodium benzoate, because methyl benzoate was unavailable. Only information on methyl benzoate nitration seems to be available. Does anyone have any info on this reaction (product [ortho, para, meta, etc.), reaction mechanism, etc.)? I see only information on methyl benzoate. Thanks.

Hi all I need to determine the amount of acid in guacamole at different pH levels. Our autotitrator has broken so I must do it manually. Problem is I've not done a titration in the last 5 years or so and also, as it's with guacamole, I'm not sure how much to dilute it or what to use as an indicator. Could anyone give me some guidance on the best way of going about this please? Thanks very much:)

Where would an electrophilic aromatic substituion most likely occur in this molecule? I assumed the ether is activating through resonance, and thus ortho/para directing. I am confused as to whether the methyl group or the ether is more activating, but I guessed that the EAS would occur at carbon A because that ring has more electron density than the other ring due to the methyl group (more stable carbocation). Is my logic correct or did I get this question wrong?

If I've this two following solutions: A - 0,5g of KIO3 in 250 mL of H2O; B - 1g of starch dissolved in 250 mL of boiling H2O. Add 0,2g of NaHSO3 and 5 mL of sulfuric acid 6M solution. Dilute in 500 mL of water. And if I mix it, will the reaction be endothermic or exothermic? Thanks. (excuse I post this topic in organics. I do not perceived it)

What is the name of the alkane? I circled it in red. I am having trouble.. Thanks!!

Cannot find the non-systematic names of these aromatic compounds online but they keep coming up in exam papers help would be greatly appreciated. Its question 2b in the attatched file. http://rapidshare.com/files/406988830/CM2006Sum2010.pdf

Can I make Dimethyl formamide by following method? Dimethyl amine hydrochloride is distilled with sodium formate to give Dimethyl formamide. It is reported for acetamide in other website.

i am new to the biogas process,i have rudimentary knowledge,but i understand the process,biogas contains;O (0-2%),CO2(30-40%),N(1-2%),H(5-10%),H2S(trace),CH4(50-70%),H2O vapour,in processing a molecular sieve(3A) could be used to filter the gas stream leaving CH4,H2S and H2O,which then could be ''scrubbed'' with activated carbon,leaving CH4 and H2O to be stored and used as fuel,from the molecular sieve the combined O,CO2,N,H could be water scrubbed to remove CO2,my question is this,could the O,N,H also be burned as fuel?any help is appreciated,thanks

Ethylene vinyl acetate is a major component in glues and i am carrying out some studies on cleaning of dried glue. The glue used predominantly Ethylene Vinyl Acetate, along with some additives. It is a water based emulsion. I am investigating the dissolution of solidified (dried) glue when suspended in solvents and ultrasound. Glue in its normal state readily dissolves in water when subjected to ultrasound. The same glue was left to dry out and then subjected to ultrasound in water. The ultrasound is unable to break the solidified layer. Alkaline water too is unalble to dissolve the dried glue. Because the cleaning was targeted at dried glue, water was deemed…

Please I need the detallied mechanism of the reduction of carboxylic acids using BH3-THF ? Thanks for any help

Hi I'm currently studing the OCR Salters Advanced Chemistry Course at school, and about to start the A2 Individual Investigation. Amongst the ideas I have, I am most interested in looking at organic synthesis of a compound. In terms of the practical content it would get me high marks as the techniques used could/will include reflux, distilation etc. However, I can not think of any significantly hard calculations that i could do to go along side the work, except calculating percentage yield. There are many marks available for calculations that are fairly complicated, so if possible could i have some suggestions on what I could calculate from synthesising a compund …

Anyone know if reactions of this type are possible? I know organo-maganesium compounds often form nasty conglomerates. If anything prevents this reaction from working, it probably has to do with the complex Shlenck equillibrium.

Everything I read says that maleimides react with thiols above pH 6.5 but I can't find any references actually showing that they won't react below pH 6.5. Will they? And if not, why not? Thanks Jo (a frustrated biologist wishing she'd paid more attention in chemistry class:rolleyes:)
