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....

6) In the synthesis of bromopropane we used NaBr and H2S04. Why the reaction does not work with only NaBr? 7) The following is a reaction you will see in second semester organic chemistry. The molecular weight of methyl benzoate is 136.16 g/mol and the molecular weight of the product is 181.15 g/mol. COCH3 COCH3 HNO3 i H2SO4 NO2 methyl benzoate methyl 3-nitrobenzoate Assume you have excess acid and you start off with 2.4 g of methyl benzoate. What is...

S RROwn as nucleophilic addition. The C-O bond is highly polarized, making carbonyl compounds electrophilic at carbon. If the Grignard reagent reacts with an aldehyde, ketone or ester, the ultimate product is an alcohol. Overall Reaction 0 Br Me PartA Part B Pre-lab questions (15 points) Show the mechanism of the reaction of bromobenzene with magnesium metal in anhydrous diethyl ether There are many inert solvents that could be used but diethyl ether was chosen because it can assist the...

2. Not only does an aromatic ring itself affect the reactivity of an acid derivative (an ester, on last year's quiz), substituents on the aromatic ring can further modify the reactivity. First, we will consider a phenyl amide with a para-acetyl substituent: CH, (a) What is the n-effect (resonance) of the para-acetyl substituent? How will that affect the reactivity of the other (amide) carbonyl in the molecule below (increase or decrease, compared to the same amide but with no p-...

Please do it soon.
4. a. We discussed leukocyte extravagation. How does the white blood cell of a patient know there is an infection nearby? The white cells will detect unfamiliar structures of the bacteria and consider it foreign. Ourbody will increase phagocytosis. It helps attack the bacteria. And destroys other cells. b. In another patient, assume cells in the trachea and upper respiratory regions of the lungs have a Covid-19 infection. White blood cells are needed there. Speculate how...

Please help! For the reaction
in step 2, how do i find the theoretical yield of the product for
this reaction? 0.07 moles of the reactant (ethyl acetoacetate
ethylene ketal) was used. What is that keto alcohol product
(circled) called? what is the molar mass of that circled product??
thank you!!

Four basic reasons for US healthcare expenditures being so high are discussed in the Lecture notes....
Four basic reasons for US healthcare expenditures being so high are discussed in the Lecture notes. These are: 1. The US does not regulate the price for healthcare services – using, in most cases, a free market approach to determine prices. 2. We are getting older as a society – and age and cost go up together. 3. We are not a very healthy nation – the consequences of a number of lifestyle choices contributes to the high cost of...
