Including all intermediates, what is the stepwise mechanism for the
synthesis of benzocaine when ethanol is added first to PABA in the
following reaction?

How do I calculate the theoretical yield and percent yield of
the reaction below?
I used 0.120 g of 4-aminobenzoic acid, 2.0 mL of ethanol, and
0.5 mL of concentrated sulfuric acid
The mass of the final product was 0.42 g
to O CH2CH2OH o H2N- HN OH H2SO4 OCH CH3 4-Aminobenzoic acid Benzocaine
Can you explain how to find what is the theoretical yield, and the desired percent yield...
Can you explain how to find what is the theoretical yield, and
the desired percent yield of ethyl 4-nitrobenzoate?
1. Synthesis of ethyl 4-nitrobenzoate a) In a 50-ml round-bottom flask, weigh out 4-nitrobenzoic acid (0.85 g, 0.005 mol). Add to this 8 ml of absolute ethanol. Add boiling stones, and then bring this solution to the Lab Technologist. WATER OUT b) The Lab Technologist will deliver 1.2 ml of concentrated sulfuric acid to the mixture from the automatic pipette. [CAUTION,...

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!!

What is the theoretical yield (in grams) and percent yield of your
triphenylmethanol product in this experiment? (Weight of
triphenylmethanol: 0.060g)
BACKGROUND AND THEORY The Grignard reaction was one of the first organometallic reactions discovered and is still one of the most useful synthetically. By reacting an organohalide (usually a bromide) with magnesium in ethereal solvent, carbon becomes a nucleophile. Grignard reagents are the starting points for the syntheses of many alkanes, primary, secondary, and tertiary alcohols, alkenes, and carboxylic...

what is the theoretical yield for this experiment?
ORGANIC POLYMERS: THE SYNTHESIS OF NYLON Nylon's outstanding characteristic in the textile industry is its versatility. It can be made strong enough to stand up under the punishment tire cords must endure, fine enough for sheer, high fashion hosiery, and light enough for parachute cloth and backpacker's tents. Nylon is used both alone and in blends with other fibers, where its chief contributions are strength and abrasion resistance. Nylon washes easily, dries...

EXPERIMENT7 PREPARATION OF PHARMACEUTICALS Fischer Esterification Reactions Almost 2500 years ago, physicians such as Hippocrates recommended that patients chew on the bark of the willow to alleviate pain. The active ingredient in willow bark was found to be salicin, a compound made of a molecule of salicyl alcohol bonded to a p-D-glucose molecule. In the stomach, the bond between...
