Draw an arrow pushing mechanism and find the theoretical yield
for the Grignard reaction below using the following amounts of
reagent with the given molecular weights:
565 microliters of 2-bromopropane (molecular weight =
123g/mol)
304 microliters of 4-methoxybenzaldehyde (molecular weight =
136.15g/mol)
molecular weight of product = 180.27g/mol
The
limiting reagent is _____________.
In this experiment, you will prepare the Grignard reagent isopropyl-magnesium bromide from 2-bromopropane. You will allow this Grignard reagent to react with 4-methoxy-benzaldehyde to form a secondary...
mechanism of (trans)-(1S, 2S) -2-méthylcyclohexan-1-ol with Br-
a) When the (trans) - (1S, 2S) -2-methylcyclohexan-1-ol is placed in the presence of hydrobromic acid diluted in water at room temperature, the substrate undergoes a substitution reaction. The speed of the reaction only depends on the concentration of the substrate. The optical activity of the substitution result deflects polarized light. Suggest a reaction mechanism which is consistent with the information provided and which clearly shows the spatial configuration (3D mechanism) of the starting substrate and that of the products....
