What happens when benzamide treated with bromine in KOH solution?

C6H5CONH2 on treating with Br2/KOH gives Aniline C6H5NH2 ( compound B) .,,Hofmann rearrangement. C6H5NH2 on treating with NaNO2/HCl gives Benzene diazonium chloride C6H5N2Cl (compound C).

What happens when benzamide is heated with bromine and KOH?

Benzamide on heating with $B{{r}_{2}}$ and KOH gives aniline. This reaction is known as Hoffmann bromamide degradation. Note: When an amide is reacted with bromine in an aqueous solution containing a strong base to give a primary amine is known as Hoffmann Bromamide Degradation.

What will be the product when benzamide reacts with bromine in presence of Naoh?

When benzamide is treated with bromine and aqueous sodium hydroxide, an aniline with one fewer carbon atom than the original amide is formed. Reaction involved is as follows: The Hofmann bromamide/degradation reaction is the name for this reaction. Aniline (C6H5NH2) will be the end product.

What happens when benzamide is heated with bromine in the presence of alkali?

– Degradation of benzamide with bromine in alkaline solution gives aniline. This reaction is Hoffmann bromamide degradation.

What happens when benzamide is heated with bromine?

when benzamide reacts with bromine in presence of KOH, the reaction is known as Hoffmann Bromamide/degradation reaction . In this reaction the CO bond is removed from the compound .

When benzamide is treated with br2 in presence of Aquascape then the end product formed is?

54. When benzamide is treated with Br, in presence of aqueous KOH then the end product formed is NH, NH Br 11.

What happens when benzamide is heated?

When benzamide is heated with dilute mineral acid we get benzoic acid and a salt ammonium chloride as products. As a mineral acid is used generally hydrochloric acid so along with formation of corresponding acid an inorganic salt is also formed.

Which of the following will give a precipitate with excess bromine water?

Phenol
Phenol is an organic compound that has an alcohol group attached to the benzene ring. Adding excess bromine water to the compound will result in Bromination and will give a white precipitate.

Which compound on reaction with br2 anyway gives Benzylamine as major product?

Which compound on reaction with Br/NaOH gives benzylamine as major product? e answer: Oro.

What is the name of the reaction when benzamide changes into?

We can change benzamide to aniline by Hoffmann bromamide reaction. In this, primary amide to a primary amine has one carbon atom less than the original amide on heating with mixture of Br₂ in the existence of NaOH or KOH (i.e. NaOBr or KOBr) is called Hofmann bromamide reaction.

Which product is obtained when dehydration of benzamide is carried out?

Abstract. Dehydration of benzamide to benzonitrile with phosphorus pentoxide in a microwave reactor for 1-2.5 min gave high yields (90\%) of benzonitrile.

Which of the following compounds will give white precipitate with bromine water?

Aniline. Aniline or phenylamine reacts with bromine water. During the reaction, a white precipitate is formed along with decolouration of brome water.
