AI Thread Summary
Benzylamine can be prepared from benzamide through the reduction process using lithium aluminum hydride (LiAlH4), which effectively reduces the amide to the amine. The reaction does not go to completion, resulting in a mixture that contains both benzylamine and unreacted benzamide. To separate pure benzylamine from this mixture, a flow diagram illustrating the separation process is needed. Participants in the discussion suggest using online resources like Wikipedia or chemistry websites to gather more information for the assignment. Overall, the focus is on understanding the reduction mechanism and the subsequent purification steps.

I need to answer a assignment question about how one can prepare benzylamine by reducing benzamide with LiAlH4. I read that LiAlH4 is a good reducing agent, and I understand that, but can someone explain how benzamide gets reduced?

And in the other half of the question, it says that this reaction does not go to completion, and that there is still a substantial amount of benzamide still in the product (but that it is mostly benzylamine). I need to explain with the aid of a flow diagram, how I would separate the pure benzylamine. Can anyone help me?

Please post it here, or send me a mail on: Kenneth_toerlen@hotmail.com ! Need it as soon as possible :)

thanks

Hi kenneth,

I am looking for the same thing (I am betting we are both in the same course). Not sure if we're supposed to do this though, I find the easiest way to trawl for related info in Wikipedia or chemistry websites, and piece it together.

Good luck.

TL;DR Summary: cannot find out error in solution proposed. [![question with rate laws][1]][1] Now the rate law for the reaction (i.e reaction rate) can be written as: $$ R= k[N_2O_5] $$ my main question is, WHAT is this reaction equal to? what I mean here is, whether $$k[N_2O_5]= -d[N_2O_5]/dt$$ or is it $$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ? The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...
I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
