why should grignard and organolithium be avoided in protic solvents? can you show clear examples ?
Write the mechanism of the following substitution reaction Explain why Polar protic solvents favor SN1 reactions. Do you expect this substrate to react under SN1. explain your answer.
I know that Grignard reagents can react with alcohol, BUT why can't we generate a Grignard reagent from a molecule containing an OH functional group? Could you use an example or a mechanism to explain this concept?
i need help with the prelab questions please Grignard reagent THE GRIGNARD REAGENT-PREPARATION AND REACTION In this experiment, you will prepare a Grignard reagent, phenyl magnesium bromide, from bromobenzene and magnesium metal. The Grignard reagent will then react with methyl benzoate to form triphenylmethanol. Introduction Grignard reagents, such as organomagnesium halides, were discovered in 1910 by French chemist Victor Grignard. The Grignard reaction is one of the most general methods for carbon- carbon bond formation in all of organic chemistry....
4. The illustrative examples should show you that the simple fixed point iterations can be very slow, An alternative algorithm can be derived by using Newton's method. Suppose that A is symmetric and show that if A is equilibrated by D(x) thern Show that ef = D(x)A + D(Ax). and hence derive a Newton method for solving the symmetric equilibration problem and write a MATLAB function to carry it out. It should have the same input and output variables as...

Describe at least four practices that should be avoided during pregnancy. What would you suggest to a newly pregnant friend who asks you specifically for nutritional advice? Describe some of the nutrient and immunological attributes of breast milk. Tell why solid food is not recommended for an infant during the first few months of life, and define when the child is ready to start eating solid food. Describe several problems associated with childhood obesity and the strategies for preventing and...
You can use an infinite amount of starting material, grignard reagents seem to be the best way to break them apart and use them later in the reaction. For D you can use any 1 Carbon reagent that does not originate from the starting molecule. Q1. Synthesize the following product from the given starting compounds. This will require more than one step. You may use any organic or inorganic reagent to carry out this synthesis but all source of carbon...
If you hold a typical pair of glasses over a table, with overhead lighting, the lenses produce a shadow on the surface. Why should clear lenses produce a shadow?

show me the work in a clear hand writing so i can understand please. The Mole (1.5 pt) If you plan to dissolve 0.075 moles of sucrose (C12H22011) to make 150 mL of solution... > (a) How many grams of sucrose should you plan to measure out? (b) What is the molarity of the resulting solution?
