What is the actual electrophile in the nitration of methyl benzoate reaction?
Nitric and sulfuric acid react to form the nitronium ion electrophile. Nucleophilic π electrons attack the nitronium ion giving methyl 3-nitrobenzoate.
What is the product of nitration of methyl benzoate?
Nitration is the substitution of an NO2 group for one of the hydrogen atoms on a benzene ring. In this experiment the students nitrate methyl benzoate. The reaction is regioselective and produces predominantly methyl 3-nitrobenzoate.
What type of reaction is the nitration of methyl benzoate?
Nitration of methyl benzoate will form a major product, methyl m-nitrobenzoate that was further purified by re-crystallization….The Nitration Of Methyl Benzoate Biology Essay.

Why does the nitration of methyl benzoate occur in the meta position?
Due to the presence of an electron-withdrawing group that is ester group ( -COOCH3 ) on methyl benzoate, the electron density at ortho and para position is less and incoming electrophile will attack position where the electron density is high that is at the meta position.
What is the limiting reagent in the nitration of methyl benzoate?
Methyl benzoate is the limiting reagent, and 2.20×10-3 mol is the theoretical yield.
What type of reaction is nitration?
In technical terms, nitration is actually part of a reaction type known as electrophilic aromatic substitution (EAS).
What are electrophilic substitution reactions?
An electrophilic substitution reaction is a chemical reaction in which the functional group attached to a compound is replaced by an electrophile. The displaced functional group is typically a hydrogen atom.
Why does nitration occurs in the meta position?
Resonating structure of nitrobenzene shows +ve charge develops in ortho and para positions. As a result, the electron density at meta position is relatively higher than at the ortho and para position. So, electron deficient electrophile always attacks at meta position.
Why the experiment nitration of methyl benzoate was conducted at a very low temperature of less than 0 C?
Explain briefly why the experiment was conducted at a very low temperature of less thanO °C. -The experiment needs to be conducted at very low temperature because nitration is arapid reaction which is 25 times faster. Thus, low temperature is applied to avoidmore than one nitro group is substituted during the reaction.
What is the molar mass of methyl benzoate?
136.15 g/molMethyl benzoate / Molar mass
Is methyl benzoate more polar than methyl M Nitrobenzoate?
Among the given compounds, Methyl benzoate is less polar than Methyl nitrobenzoate. This is because Methyl nitrobenzene contains an additional polar group (-NO₂) which increases its polarity.
What is nitration reaction and which functional groups can be nitrated?
In organic chemistry, nitration is a general class of chemical processes for the introduction of a nitro group into an organic compound. The term also is applied incorrectly to the different process of forming nitrate esters between alcohols and nitric acid (as occurs in the synthesis of nitroglycerin).
What is the difference between methyl benzoate nitration and acetanilide nitration?
The methyl benzoate nitration formed white solid, and the acetanilide nitration for a light yellow solid. The crystals were the vacuum filtered with a Buchner funnel.
What is the yield of acetanilide and methyl benzoate?
Nitration of Acetanilide and Methyl Benzoate Product Name Crude Weight (g) Product Weight (g) Percent Yield (%) Melting Point (ËšC) Nitroactenilide 0.585 0.045 6.75% 195-200 Methyl Nitrobenzoate 0.56 0.32 59.3% 74-80
How do you make methyl Nitro benzoate from acetanilide?
Nitration of Acetanilide and Methyl Benzoate by Electrophilic Aromatic Substitution The purpose of this experiment was to synthesize methyl nitro benzoate from methyl benzoate, as well as nitroacetanilide from concentrated nitric acid (HNO 3), and concentrated sulfuric acid (H 2 SO 4) by using an electrophilic aromatic substitution reaction.
What is the melting point of methyl benzoate and nitroacetanilide?
Following recrystallization, melting point was used to identify and characterize the product of the reaction. The melting point was determined to be 74 ËšC-80 ËšC for methyl nitro benzoate and for nitroacetanilide it was 195 ËšC-200 ËšC, which indicates meta-regiochemistry for methyl benzoate and para-regiochemistry for nitroacetanilide.
