Nitration of Methyl Benzoate Introduction: Nitration is an example of an electrophile aromatic substitution reaction‚ where nitro (NO2) group is being substituted for a hydrogen on an aromatic compound. This is achieved by the formation of the nitronium ion by protonation of nitric acid from sulfuric acid. The zirconium ion is a strong electrophile and can react with aromatic compound such as Methyl benzoate to form an arenium ion intermediate. The arenium ion is then depronated to reform

benzene ring that a nucleophile could add to‚ referred to as the ortho‚ para‚ or meta positions. In this experiment‚ the nucleophile will primarily add into the meta position. This is because the starting material is methyl benzoate‚ as opposed to just benzene. The ester group of methyl benzoate is capable of participating in the resonance of the ring. This withdraws electron density from the benzene ring‚ and is said to be deactivating. Deactivating substituents destabilize the carbocation intermediates

concentrations of orange juice. Research Question By diluting concentrated orange juice with water‚ can you significantly change the PH value? Introduction Across the world‚ it is thought and widely accepted to believe that Orange juice is the cure to many terrible diseases. However‚ this may not be true anymore. It has been said that Oranges are very high in vitamin C‚ therefore one should drink it every morning to stay healthy and prevent the symptoms of any diseases. Oranges apparently are

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

Nitration of Methyl Benzoate Abstract: This procedure demonstrates the nitration of methyl benzoate to prepare methyl m-nitrobenzoate. Methyl benzoate was treated with concentrated Nitric and Sulfuric acid to yield methyl m-nitrobenzoate. The product was then isolated and recrystallized using methanol. This reaction is an example of an electrophilic aromatic substitution reaction‚ in which the nitro group replaces a proton of the aromatic ring. Following recrystallization‚ melting point and infrared

Title: Experiment 28: Nitration of Methyl Benzoate Objective: The students will learn to nitrate methyl benzoate through electrophilic aromatic substitution reaction. They will learn the importance of regiochemistry in chemical reactions. They might experience disubstitution through a high temperature. Reactions: Observation: The crystals started to form when added 2 g of crushed ice. The addition of hot methanol dissociated the crystals. The crystals reappeared when cooled down in

ABSTRACT This experiment was conducted to synthesize methyl benzoate form benzoic acid and methanol by using the Fischer esterification method. The Fischer exterification technique is utilized in the academic and industrial settings due to the simplified synthesis and safety parameters of the overall reaction. Both benzoic acid and methanol are relatively cheap to obtain from a commercial source as well as being easy to store with a relatively long shelf life. The Fischer esterification method is
