Sarah Muhs ID: 11325862 Nitration of Methyl Benzoate Post Lab: 1. Is the ester group of your starting material electron donating or withdrawing? Support your conclusion with resonance drawings. The ester group‚ CO2CH3‚ of the starting material was electron withdrawing. 2. Draw the mechanism of the nitronium ion reaction with the methylbenzoate. 3. Why does water stop the reaction? Water stops the reaction because of Le Châtlier’s principle. Since water is a product‚ when more is added it drives

began by weighing 4.0ml of methyl salicylate into a flask—a stir bar was added. While stirring‚ 40ml of 6M sodium hydroxide was added and the solution was heated and boiled for about 15 minutes. After the 15 minutes‚ a bit of water was used to wash down the sides of the flask and the solution was cooled. It was boiled for another 15 minutes‚ after this the solution was cooled for 5 minutes in an ice water bath. While the flaks was in the ice bath‚ 50ml of 6M hydrochloric acid was added in 5ml increments

Oranges "Oranges" begins with Gary Soto narrating one of his life experiences in this poem. He remembers a particular experience of walking side by side with a girl. There are two characters a twelve year old boy and his date. When the poem begins‚ the narrator is alone‚ and on his way to go pick up the girl. It was winter time and he only had two oranges with him‚ which his purpose was to share them with his date. The beginning of the poem is not very positive‚ though‚ but rather negative. In

Lab 8- nitration of Methyl I Benzonate Date of experiment: INTRODUCTION: The nitration of methyl benzoate is an example of an electrophilic aromatic substation reaction. In the experiment the electrophile was the nitronium ion and the aromatic compound was methyl benzoate and with addition of nitrating solution Methyl 3-nitrobenzoate was the product. Methyl benzoate Methyl 3-nitrobenzoate MATERIALS AND METHODOLOGY: The procedures for this experiment

We performed two procedures in which we reduced methyl acetoacetate. For the first procedure we produced a racemic mixture of Methyl (S)-3-Hydroxyacetate and Methyl (R)-3-Hydroxyacetate. For the second we produced only one of the enantiomer products depending on which enantiomer of Tartaric Acid was used. A reduction is a reaction which generally means adding more carbon-hydrogen bonds to a compound. In a reduction reaction the oxidation number of a carbon atom decreases. The opposite is an oxidation
