Why is o-aniline phenol less soluble in water than m-aniline phenol?
In o-aniline phenol Intramolecular hydrogen bonding occurs which is not possible in meta and is responsible for less solubility
How to convert aniline to picric acid?
React aniline with HCl/NaNO2 (diazotisation) followed by reaction with KOH to give phenol. Nitration of phenol with fuming nitric acid gives picric acid (or trinitrophenol).
In lederer manasse reaction phenol is converted into?
This reaction is also called p-Hydroxy methylation of Phenol and phenol is converted into p-hydroxy benzyl alc.
What are pharmaceutical uses of aniline?
Aniline is used in the synthesis of numerous pharmaceutical compounds. It serves as a starting material for the production of various analgesics, antipyretics, and anti-inflammatory drugs. Additionally, aniline derivatives are employed in the synthesis of certain antibiotics, antimalarials, and antitumor agents.

fluorine is the most reactive

Why is it that aniline has a high boiling point to phenol and phenol has a high boiling point than toluene and toluene has a high boiling point than benzene?
Aniline has a higher boiling point than phenol because aniline can form strong hydrogen bonds due to the presence of an amino group. Phenol has a higher boiling point than toluene because phenol molecules can form intermolecular hydrogen bonds because of the hydroxyl group. Toluene has a higher boiling point than benzene due to the presence of a bulky methyl group which increases Van der Waals forces between toluene molecules.

What is the name of C6H5COOC2H5?
The formula is for benzyl acetate (as an example).
What is the reaction mechanism of phenol into aniline?
Phenol is converted to aniline via the Zinin reduction reaction, which involves the reaction of phenol with ammonia and sodium metal. The phenol first forms a sodium phenoxide intermediate, which reacts with ammonia to give an amine salt. Finally, the amine salt is then reduced by sodium metal to produce aniline.
If Nitrobenzene has a larger dipole moment then aniline and phenol but is much less soluble in water?
aniline and phenol can form hydrogen bonds with water molecules through their -NH2 and -OH groups, while nitrobenzene has no available hydrogens, but in principle can form hydrogen bonds with its oxygens with water hydrogen.As a matter of fact, the first option is more favorable than the second (e.g. butanol CH3CH2CH2CH2-OH is slightly more soluble than butanal CH3CH3CH2HC=0 in water, and the difference in solubility increases at increasing alkyl chain length).On a qualitative basis, one can think that aniline and phenol are more similar to water than nitrobenzene, hence they are more miscible.

In estimation of aniline why we can add brominating mixture?
Adding a brominating mixture to aniline allows for the conversion of aniline to p-bromoaniline. This reaction modifies the properties of aniline, making it more suitable for quantitative estimation using techniques like titration or gravimetric analysis. The bromination reaction also helps in separating aniline from other components present in the sample.
What are the differences between phenyl and phenol, and how do they affect the properties and reactivity of organic compounds?
Phenyl is a hydrocarbon group with a benzene ring, while phenol is a hydroxyl group attached to a benzene ring. Phenol is more reactive due to the presence of the hydroxyl group, which can participate in hydrogen bonding and other reactions. Phenyl, being a simple hydrocarbon group, is less reactive in comparison. The presence of the hydroxyl group in phenol can also affect the solubility and acidity of organic compounds.
What are the key differences between phenol and benzene in terms of their chemical properties and reactivity?
Phenol and benzene are both aromatic compounds, but phenol has a hydroxyl group (-OH) attached to the benzene ring, making it more reactive than benzene. Phenol can undergo reactions such as oxidation and substitution more readily than benzene. Additionally, phenol is more acidic than benzene due to the presence of the hydroxyl group.
Why phenol is more reactive than anisol?
Phenol is more reactive than anisole because the hydroxyl group in phenol is a stronger activating group compared to the methoxy group in anisole. The resonance stabilization of the phenoxide ion formed during reactions further enhances its reactivity. In contrast, anisole's methoxy group is a weaker activating group and does not stabilize the negative charge as effectively.
