What is the reagent catalyst and solvent from aniline to acetanilide?
To convert aniline to acetanilide, the reagent used is acetic anhydride or acetyl chloride. The reaction typically requires a catalyst such as a base, like pyridine, to facilitate the acetylation. The solvent can be a non-polar organic solvent like dichloromethane or toluene, although the reaction can also proceed without a solvent.
What reagent is used to test for unsaturated hydrocarbons?
This reagent is bromine in solution.
What is aniline derivatives?
Aniline derivative is a chemical precurser and is used in many haircoloring products as well as polyurithane(spelling subject to correction) due to its oxidative properties. As far as i know.
What is formed when phenol reacts with Hinsberg reagent?
Hinsberg reagent is used for amines.
What chemical reagent of protein?
Biuret reagent is used to test for protein in urine. It is a common test that students in biology class perform. Urine is added to a test tube, followed by approximately the same amount of Biuret reagent. If the solution turns lavender this means that there are proteins present in the urine.

What is the impurity formed during the preparation of the Grignard reagent if phenyl bromide was used instead of bromobenzene?
If phenyl bromide is used instead of bromobenzene in the preparation of a Grignard reagent, the impurity formed is phenylmagnesium bromide (PhMgBr). This impurity can be problematic because it reacts differently than the desired Grignard reagent and can lead to undesired side reactions. This impurity can be removed through careful purification techniques before further use in reactions.
How do you convert aniline to phenol?
Use acetic anhydride as reagent. The reaction will undergo nucleophilic addition and the reagent will attach to the amine group. Half of the reagent will become the leaving group and one H of the amine group in the reactant will leave with the reagent. The product will be the benzene ring with an amine, carbonyl, methyl attached.
What is bromobenzene used for?
Bromobenzene is a clear, colorless liquid with a pleasant odor. It is used as a solvent and motor oil additive, and in making other chemicals.
A substance used to detect or measure another substance or to convert a substance into another?
a reagent
What is the role of KI in the estimation of aniline?
ki is added to liberate iodine gas . this liberated iodine gas was then titrated with sodium thiosulphate to give a permanent white precipitate. this white precipitate indicates the endpoint of the titration..
Which oxidising agent used for polymerization of aniline?
Potassium dichromate, Ammonium peroxidisulphate, Hydrogen peroxide can be used for polymerization of aniline.
How can one make a Wittig reagent?
To make a Wittig reagent, one can react an aldehyde or ketone with a phosphonium ylide. This reaction forms a carbon-carbon double bond, which is the key feature of a Wittig reagent. The resulting compound can be used in organic synthesis to convert carbonyl compounds into alkenes.
Why aniline doesn't under go friedal craft reaction?
Aniline doesnt undergo friedel craft rxn because the reagent AlCl3,(the lewis acid which is used as a catalyst in friedel crafts reaction).being e- deficient acts as lewis base and attacks on the lone pair of nitrogen present in aniline & aniline forms a salt with Aluminium chloride. Due to this nitrogen atom of aniline acquires a positive charge and hence acts as a strong deactivating group and thus doesn 't allow the reaction to take place.In other cases ther is no such reaction.
What is the importance of sodium hydroxide in the preparation of bromoaniline?
Sodium hydroxide is used in the preparation of bromoaniline as a base to deprotonate the aniline compound, making it more reactive towards the brominating reagent. This reaction typically involves a substitution of a hydrogen atom on the aniline molecule with a bromine atom. Sodium hydroxide helps facilitate this reaction by providing the necessary basic conditions for the deprotonation step.
How do you convert aniline into 246 tribromoanaline?
To convert aniline into 2,4,6-tribromoaniline, you can employ bromination using bromine in the presence of a suitable solvent, such as acetic acid or carbon tetrachloride. Aniline's amino group (–NH2) is an activating and ortho/para-directing group, facilitating the substitution of bromine at the 2, 4, and 6 positions on the aromatic ring. Typically, bromination is done in a controlled manner to ensure multiple substitutions occur, leading to the desired tribromo product. After the reaction, purification methods such as recrystallization can be used to isolate 2,4,6-tribromoaniline.
Is it wfi used for inplace of lal reagent water?
The LAL reagent water can be sterile WFI or other water that show reaction with the specific LAL reagent with which it can be used, at the limit of the sensitivity of such reagent.
