Do ortho nitro phenol and para nitro phenol have hydrogen bonding in their molecules?
Yes, both ortho nitrophenol and para nitrophenol have hydrogen bonding in their molecules due to the presence of the -OH group, which can participate in hydrogen bonding with other adjacent molecules.
Why para-nitro acetanilide is insoluble in water whereas ortho-nitro acetanilide is soluble in water?
p-nitro phenol has a symmetric structure as compare to o-nitro phenol so it has higher dipole moment or polarity so is more soluble.
Why are two isomers produced in the nitration of phenol?
In the nitration of phenol, two isomers are produced due to the presence of two different positions on the benzene ring where the nitro group (-NO2) can attach. These two isomers are ortho-nitrophenol (2-nitrophenol) and para-nitrophenol (4-nitrophenol), formed when the -NO2 group attaches to the ortho and para positions of the phenol ring, respectively.
Why nitro group is formed on ortho and para position?
orientation of incoming Nitro group is destined by already present group on benzene ring . if already present group is electron donating group, it will promote electron density at ortho and para position and , therefore, nitro group is formed on ortho and para position.
Which is more acidic phenol or para-chloro phenol?
Phenol. Anisole doesn't have any acidic protons.
How can seprate p-nitro acetanilide mixture of para and ortho acetanilide?
The amide group on acetanilide is an ortho/para director, so a simple nitration should work: a mixture of sulfiric acid and nitric acid should be sufficient. Afterward, separation of the ortho and para compounds (by column chromatography, probably) would be necessary.
Can phenol be oxidized?
Yes. Phenol can be oxidized by hydrogen peroxide to form ortho and para benzenediol with the by product being water. Chromic acid can also oxidize phenol into quinones.
Is the substituent SO3H ortho para directing?
Yes, the substituent SO3H is ortho para directing.
What is the reaction of phenol with Bromine?
The hydroxyl group in phenol is an activating ortho/para director, but has some slight steric hindrance too ortho position substitution. Therefore, the predominant product of reaction between phenol and bromine will be 4-bromophenol, if reaction conditions are carefully controlled. With excess bromine, di- and tri-bromo phenols will be formed.
Is the director of the ortho para department an experienced professional in the field?
Yes, the director of the ortho para department is an experienced professional in the field.
Are halogens ortho para directors in organic chemistry reactions?
Yes, halogens are ortho para directors in organic chemistry reactions.
How do you separate para nitroacetanilide from ortho nitroacetanilide?
Para-nitroacetanilide and ortho-nitroacetanilide can be separated by utilizing their different solubilities in various solvents or through techniques such as column chromatography or fractional crystallization. For example, para-nitroacetanilide is more soluble in organic solvents like acetone or ethyl acetate compared to ortho-nitroacetanilide, which allows for their separation based on solubility differences. This can enable the isolation of each compound for further analysis or purification.
