An alcohol reacts with acetic anhydride in NaOH/H20 to yield a(n) _______. alkene amide ester carboxylic...
An acid anhydride reacts with an alcohol to form one ester and one carboxylic acid. An unsymmetrical acid anhydride can react with alcohol at either carbonyl carbon, so there are two possible esters and two possible carboxylic acids. Draw the structures of all possible organic products formed in the following reaction. Do not draw counterions or byproducts. CH3 OH CH3 НАС CH3 CH3 HO So
In the Fischer esterification reaction a carboxylic acid reacts with an excess of alcohol in acidic conditions to form an ester. During the reaction the sp2 hybridized carbonyl carbon of the acid forms an sp3 hybridized intermediate before returning to sp2 hybridization in the product. Draw the structure of the neutral sp3 hybridized intermediate and the ester product in the reaction between pentanioc acid and n-propanol. Which reactant provides the oxygen atom found in the ester linkage: Pentanoic acid, or...
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...
Calculate the theoretical yield and percent yield for experiments 7, 8, and 9. For experiment 9, determine the theoretical yield based on starting with 0.50g of 3-nitrobenzoic acid. Show work Acid I (experiment 7): Weight of methyl 3-nitrobenzoate = 1.9 g Acid II (experiment 8): Weight of 3-nitrobenzoic acid = 1.75 g Acid III (experiment 9): Weight of 3-nitrobenzamide = 0.30 g Experiment 7: -2.5 mL concentrated H2SO4 -1.75 mL concentrated HNO3 (16M) -2.1 mL concentrated Methyl Benzoate Experiment 8:...
QUESTION 3 Salicylic acid reacts with acetic anhydride to form aspirin and acetic acid as shown. Use the equation to answer Questions 3 – 6. (salicylic acid) (aspirin) C7H6O3 (s) + C4H6O3 (l) → C9H8O4 (s) + CH3COOH (l) MM = 138 MM = 180 If we divide 180 by 138 we find that 1.00 g salicylic acid will produce a maximum of 1.30 g aspirin. 3. A student starts with 3.20 g salicylic acid. What is the maximum amount...
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....
What is the correct name for the following compound? d) 5-oxo-3-octenoic acid What is the defining functional group of a carboxylic acid? a) an-H attached to a carbonyl group b) an-H attached to a carbon-carbon triple bond c) an-OH attached to a carbonyl group d) an -OH group attached to a O-C double bond e) an-OH group attached to an aromatic ring To convert a carboxylic acid to an aldehyde a) convert the acid to an acid chloride, then use...
1. 2. JUST DRAW ARROWS... (CH3)2Culi + CH3Cu Ph CI Ph CH3 The ketone intermediate formed in the reaction of an acid chloride with a Grignard reagent cannot be isolated because it reacts too rapidly with the second equivalent of Grignard reagent. To produce a ketone from an acid chloride, one can treat the acid chloride with a lithium dialkylcopper reagent. The reaction occurs by nucleophilic acyl substitution on the acid chloride by the dialkylcopper anion to yield an acyl...
