What is the product formed from the nitration of 1,2-dimethoxybenzene ( veratrole)? What would be the equation for the reaction.
Details. Veratrole was mixed with glacial acetic acid.This mixture was then added dropwise to a solution of nitric acid and water.
4-nitro-veratrole
To determine the product formed from the nitration of 1,2-dimethoxybenzene (veratrole) and write the equation for the reaction, we need to understand the process of nitration and the reactivity of the reactants involved.
Nitration is a chemical reaction in which a nitro group (-NO2) is introduced into a molecule. In this case, we are nitrating veratrole (1,2-dimethoxybenzene) using a mixture of glacial acetic acid, nitric acid, and water as the nitrating agent.
The reaction for the nitration of veratrole can be understood as follows:
1. Write the structural formula of veratrole: CH3OC6H4OC2H5.
(The molecule has two methoxy groups, represented as -OCH3, attached to a benzene ring.)
2. The nitration reaction involves the replacement of one of the hydrogen atoms on the aromatic ring with a nitro group (-NO2). The nitro group is formed by the reaction between nitric acid (HNO3) and sulfuric acid (H2SO4).
The overall reaction can be represented as:
CH3OC6H4OC2H5 + HNO3 → Product + H2O
3. The mechanism involves the electrophilic substitution of the aromatic ring. The nitronium ion (NO2+) is the electrophile that reacts with the benzene ring.
4. In nitrations, the electron-donating groups on the ring (such as methoxy groups) direct the incoming substituent to the ortho or para positions (relative to the methoxy groups). In this case, the product is ortho or para-nitroveratrole.
The equation for the overall reaction can be written as:
CH3OC6H4OC2H5 + HNO3 → CH3OC6H4ONO2C2H5 + H2O
Therefore, the product formed from the nitration of 1,2-dimethoxybenzene (veratrole) is ortho or para-nitroveratrole (CH3OC6H4ONO2C2H5).
