Aniline can be converted into phenyl hydrazine by reacting it with hydrazine hydrate in the presence of an acid catalyst such as hydrochloric acid. The reaction proceeds through the formation of a diazonium salt intermediate, which then reacts with excess hydrazine to form phenyl hydrazine.
What else can I help you with?
Why is phenylhydrazine a better neuclophile than aniline?
Yes, in phenyl hydrazine the electron pair on terminal nitrogen is always available for attack while in analine the electron pair of nitrogen is less available due to involvement in resonance process with benzene ring.
What are two aldotetroses that yield the same osazone on reaction with phenyl hydrazine?
D-erythrose and D-threose both yield the same osazone. Likewise, L-erythrose and L-threose yield the same osazone.
How do you convert toluene to aniline?
To convert toluene to aniline, you can first nitrify toluene to form nitrotoluene using a mixture of concentrated nitric and sulfuric acids. Then, the nitrotoluene can be reduced to aniline through catalytic hydrogenation or using reducing agents like iron and hydrochloric acid or lithium aluminum hydride. This process involves the substitution of the nitro group with an amino group, resulting in the formation of aniline.
What happens when methanal is treated with phenyl hydrazine?
When methanal is treated with phenylhydrazine, it forms a yellow-orange crystalline compound called phenylhydrazone. This reaction is commonly used as a qualitative test for the presence of methanal in a sample.
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).
Molecular formula of phenyl hydrazine?
C6h8n2
How do you convert c6h5nh2 to c6h5ococh3?
To convert aniline (C6H5NH2) to phenyl acetate (C6H5OCOCH3), you can follow these steps: First, acetylate aniline using acetic anhydride or acetyl chloride, which will replace the amino group with an acetyl group, forming acetanilide (C6H5NHCOCH3). Next, you can hydrolyze the acetanilide with an acid or base to yield phenyl acetate. This process involves replacing the amine group with an ester group, ultimately giving you C6H5OCOCH3.
What is the composition of the organic compound aniline?
The composition of the organic compound aniline is the prototypical aromatic amine, consisting of a phenyl group attached to an amino group. It's main use is in the manufacture of precursors to polyurethane.
What are two aldotetroses that yield the same osazone on reaction with phenyl hydrazine?
D-erythrose and D-threose both yield the same osazone. Likewise, L-erythrose and L-threose yield the same osazone.
Why is phenylhydrazine a better neuclophile than aniline?
Yes, in phenyl hydrazine the electron pair on terminal nitrogen is always available for attack while in analine the electron pair of nitrogen is less available due to involvement in resonance process with benzene ring.
How can you distinguish aniline and primary amine?
Aniline is a specific type of primary amine that contains a phenyl group attached to the amino group. One way to distinguish them is by performing a diazo coupling reaction, where aniline will give a colored dye, whereas a simple primary amine will not show this reaction. Additionally, aniline can be distinguished by its distinctive smell and the fact that it can undergo aromatic electrophilic substitution reactions due to the presence of the phenyl group.
What is the product of potassium thiocyanate reacts with aniline in presence of bromine in acetic acid?
The reaction of potassium thiocyanate with aniline in the presence of bromine in acetic acid will result in the formation of 2-phenyl-4,5-dihydro-1H-imidazole-1-carbothioamide.

How do you Prepare sulphanilic acid from phenyl amine?
To aniline, we add Sulphuric acid at 180.C. This will give us Sulphanilic acid. C6H5NH2+H2SO4-------->C6H5 NH3+HSO4-------455 to 475.K-----> C6H5NH2SO3H <=>C6H5NH3+SO3- (zwitter ion)
What is the Prepration of phenyl benzoate from phenol?
To prepare phenyl benzoate from phenol, first convert phenol to phenyl benzoate by reacting it with benzoic acid and a catalyst such as concentrated sulfuric acid or concentrated hydrochloric acid at elevated temperatures. This esterification reaction will yield phenyl benzoate along with water as a byproduct. Purification techniques such as distillation can then be used to isolate the desired product.
How do you convert aniline to benzamide?
Aniline can be converted to benzamide by reacting it with benzoyl chloride in the presence of a base, such as pyridine, at room temperature. This reaction forms a carbamate intermediate which then undergoes hydrolysis to produce benzamide.
