Do ortho nitro phenol and para nitro phenol have hydrogen bonding in their molecules?
Otho nitro phenols have intra cellular H bonds.Para nitro phenols have inter cellular H bonds.
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 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.
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.
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.
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.
Ortho - hydroxyacetophenone vs para - hydroxyacetophenone polarity?
para is more polar than the ortho
How can you prepare para-nitro acetanilide from acetanilide?
used of para nitro acet anilide
Why is orthonitro phenol more volatile than its corresponding meta and para isomers?
Since there is intramolecular hydrogen bonding between -OH and -NO2 groups, present in the ORTHO-nitrophenol (they are very close to each other), these ortho-molecules do NOT attrack each other so much by intermolecular forces caused by hydrogen bonding as is the case with meta- and para-nitrophenol.
Why methyl attached to benzene is ortho-para director group?
This group attached to benzene ring acts as the ortho-para directing group due to Hyperconjugation.
What is ortho meta and para in benzene?
ortho-para in benzene is meaningless these positions are for monosubstituted benzene. Meta is positions 3 and 5. Ortho is position 2 and 6 with relation to already attached group, para is 4 (opposite) to attached group.
