AdministratorWhat is the intermediate formed in the nitration of methyl benzoate?
The solvent of the nitration which is the sulfuric acid will protonate the reagent, methyl benzoate, which will create stabilized carbocation intermediate. The electrophile or the electron poor nitronium ion, will react to the protonated intermediate in the meta position.
What is the melting point of methyl benzoate?
5°F (-15°C)Methyl benzoate / Melting point
How does temperature affect nitration?
At higher temperatures there is a greater chance of getting more than one nitro group substituted onto the ring. You will get a certain amount of 1,3-dinitrobenzene formed even at 50°C. Some of the nitrobenzene formed reacts with the nitrating mixture of concentrated acids.
Why use an ice bath in the nitration of methyl benzoate?
Ice is used because the reaction of concentrated acids, especially concentrated sulfuric acid, with water is very exothermic. This would lead to the hydrolysis of the ester function during this step.
What is the boiling point of methyl benzoate?
390.2°F (199°C)Methyl benzoate / Boiling point
Which of the following will undergo nitration slower than benzene?
Toluene undergoes nitration easily than benzene.
What is nitration of methyl benzoate?
Resources Nitration of methyl benzoate No comments Synthesise and recrystallize a sample of methyl 3-nitrobenzoate. Class practical Nitration is the substitution of an NO2group for one of the hydrogen atoms on a benzene ring. In this experiment the students nitrate methyl benzoate.
What is the nitration temperature of methylbenzene?
The nitration of methylbenzene (toluene) Methylbenzene reacts rather faster than benzene – in nitration, the reaction is about 25 times faster. That means that you would use a lower temperature to prevent more than one nitro group being substituted – in this case, 30°C rather than 50°C.
What is nitration of benzene?
Class practical Nitration is the substitution of an NO2group for one of the hydrogen atoms on a benzene ring. In this experiment the students nitrate methyl benzoate.
What is the purpose of this reaction between methyl benzoate and 3-nitrobenzoate?
The purpose of this reaction it’s to perform a nitration reaction on methyl benzoate to create a product of 3-nitro methyl benzoate.
