    Product Synthesis
AI Thread Summary
The discussion focuses on the solid formed when phenyl magnesium bromide is added to methyl benzoate, which is a key step in the Grignard synthesis of triphenylmethanol. Participants clarify that the product consists of a carbon atom bonded to one phenyl group from methyl benzoate and another from the Grignard reagent, resulting in a compound with two phenyl groups. The confusion arises from the naming of the intermediate product, as it does not contain three phenyl groups despite the eventual formation of triphenylmethanol. The emphasis is on accurately identifying and naming the intermediate compound before it fully converts to triphenylmethanol. Understanding the structure and naming conventions is crucial for correctly interpreting the synthesis process.

Homework Statement


What is the solid that forms during the addition of phenyl magnesium bromide to methyl benzoate (step before triphenylmethanol)?

Homework Equations


See below.

The Attempt at a Solution


I know the structure of the product, but I don't know exactly how to name it. The product has a carbon bonded to three phenyls, and the fourth bond is to OMgBr.
 
Physics news on Phys.org
There aren't three phenyls in the product. You are adding one phenyl group to methylbenzoate, which has only one phenyl group itself. If you are adding 2 equivalents of the grignard, you are correct but the question specifically asks for the product "...(step before triphenylmethanol)".

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...

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

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...
