Reaction mechanism Definition and 25 Threads

I think the answer is both A) Cl and B) CCl3, since both are produced and used up. The correct solution is only A). Could anyone explain why? Thanks.

Hello all! I wrote a reaction mechanism for a sequence that forms an amide. Do you agree with my answer? Thanks for your help!

Hey Guys, exercise: "It is desired to study the first excited state of 16O which is at energy of 6.049 MeV. Using the (alpha, n) reaction on target of 13C, what is the minimum energy of incident alphas which will populate the excited state? So, i suggest to define first the reaction equation...

This is a chemically inspired problem, but the path is fully quantum mechanics and a bunch of integrals. How does one calculate fully quantum mechanical rate ($\kappa$) in the golden-rule approximation for two linear potential energy surfaces? Attempt: Miller (83) proposes...

1. Homework Statement 2. Homework Equations rate law equation 3. The Attempt at a Solution a) I would expect this reaction to be a multi-step reaction because there are six reactant molecules, as shown in the overall chemical equation. For this reaction to be one-step, all six molecules...

I have an assignment in which I must find a named reaction, the original reference to it, and show what experimental evidence was used to develop the reactions mechanism. So far I've had no luck finding anything. It's hard enough finding the original reference and so far I haven't been able to...

Homework Statement Homework EquationsThe Attempt at a Solution Can't find this exact reaction mechanism online. Help? http://imgur.com/a/X9P7e I don't know what the mild oxidation does. Does it split the double bond into a ketone and aldehyde?

Homework Statement Please see question number 31 http://cms.fiitjee.co/Resources/DownloadCentre/Document_Pdf_183.pdf Homework Equations none The Attempt at a Solution i got up to second step in the solution(scroll downwards) but in the last step a carbocation is formed and double bond can...

Homework Statement What is the product of 1-bromo-3-propanone treated with vinyl lithium? Homework EquationsThe Attempt at a Solution I know that the carbonyl is attcked by the organolithium but I am having a hard time understanding how it attaches to the carbonyl since it is sp2 hybridized...

I am having some trouble understanding why different sources of bromine radicals supposedly brominate an alkene at different positions. What I mean by this: In the first example, the Bromine radical attacks a hydrogen at the allylic position and then a termination reaction results in a Bromine...

Can anyone please walk me through the mechanism as this question does not make sense to me. I do have some understanding of the general mechanism. The answer is B) but I don't understand how to get there. The confusing aspect to me, is the structure of the ylide.

I have this reaction mechanism but I am not sure if its correct or not. In lab we reduced the m-nitroacetophenone using tin and HCl and then using sodium hydroxide to make m-aminoacetophenone. This mechanism goes beyond the scope of our class and not sure why our lab teacher had us do it and its...

I'm in a first year organic chemistry class with a biochem focus and I am going to do a project on ketoacidosis. While I can find the pathway online, since this is an organic chemistry class, I figure that a reaction mechanism that illustrates electron movement (arrows and such) would be...

A chemical Reaction A-->B is carried out in a closed vessel. The following data are taken for the concentration of A, Ca (g/L), as a function of time, t(min), from the start of the reaction. A proposed reaction mechanism predicts that Ca and t should be related by the expression ln...

Homework Statement Consider the following mechanism: (1) ClO^{-} (aq) + H2O (l) \Leftrightarrow HClO (aq) + OH^{-} (aq) [fast] (2) I^{-} (aq) + HClO (aq) \rightarrow HIO (aq) + Cl^{-} (aq) [slow] (3) OH^{-} (aq) + HIO (aq) \rightarrow H2O (l) + IO^{-} (aq) [fast] Is the mechanism...

Write the rate law for the following proposed mechanism for the decomposition of IBr to I2 and Br2. IBr(g)---------->I(g) + Br(g) (fast) IBr(g) + Br(g)-------->I(g) + Br2(g) (slow) I(g) + I(g)--------->I2(g) (fast) The answer is R=k[IBr]^2. I don't know where this answer comes...

Homework Statement I have been working at this for about two days now and haven't really gotten any further. Unfortunately my teacher is away but last time he checked it over he said I was 'almost there' so a few extra nudges in the right direction would be appreciated! I'm trying to write...

Hi, I need help with the following question: What are mechanisms of reactions that lead to the production of ground level ozone the chemical reaction is sunlight + VOCs + NOx -> Smog and Ozone can someone tell me waht the mechanism is or how to develope the mechanism

I experimentally determined the reaction rate of the following reaction: 4HCl(aq) + 4NaS2O3(aq) -> 4NaCl(aq) + 3S(s) + 5SO2(aq) + 2H2O(l) and found that the rate was proportional to [NaS2O3]^1 and [HCl]^2 I know that it's probably too tricky to determine the reaction mechanism or rate...

Year 11 chemistry problem the whole class is stuck on and our regular teacher is away for a month: A strip of substance x(2+) is placed in a red solution of y(2+) (aq). After 3 hours the red colour becomes less intense. There is no change after this. Some x(2+) still remains. a) write a...
