1) Hydrolysis of Methyl Salicylate: Methyl Salicylate (C8H8O3) + sodium Hydroxide (NaOH) -> sodium Salicylate ( NaC7H5O3) + Methanol (CH3OH) 2) Acidification of Sodium Salicylate: Sodium salicylate (NaC7H5O3) + HCL -> Salicylic acid (C7H603) + sodium chloride (NaCL) Could you find the theoretical yield for me? 2.15g of methyl salicylate was used. 25ml of sodium hydroxide (2m solution) was used for hydrolysis and 2ml of hydrochloric acid was used for the acidification. This produced a yield of 1.53g of salicylic acid.
Using your reaction roadmap as a guide, show how to convert ethylene into 1-butene. All of the carbon atoms of the target molecule must be derived from ethylene. Show all intermediate molecules synthesized along the way.
1-butanol yields 1-bromobutane in the presence of concentrated sulfuric acid and an excess of sodium bromide. CH3CH2CH2CH2OH (l) → CH3 CH2CH2CH2Br (l) If 15.89 mL of 1-butanol produced 12.23 g of 1-bromobutane, the percentage yield of the product equals: (Assume the density of 1-butanol is 0.81 g/mL, the molar mass of 1-butanol is 74 g/mol, and the molar mass of 1-bromobutane is 137 g/mol.) %
In an experiment, triphenylmethanol is prepared using the Grignard reaction. The Grignard reaction involves preparation and reaction of a very nucleophilic organo-magnesium compound. The Grignard reagent is very reactive and is easily destroyed by reaction with atmospheric water, oxygen, or carbon dioxide. The Grignard reagent must be prepared under strict anhydrous conditions (dry glassware, dry solvent). The volative solvent, diethyl ether, helps to prevent oxygen or carbon dioxide from entering the reaction vessel. Reaction of bromobenzene with magnesium in ether produces phenylmagnesium bromide. This Grignard reagent then reacts with methyl benzoate to produce the corresponding alkoxide. Reaction of the alkoxide with aqueous acid then produces the alcohol. Why does pressure develop when the separatory funnel containing aqueous sulfuric acid and the ethereal solution of organic products is shaken?
