What happens when acetophenone reacts with NaOH?

In this typical iodoform reaction, acetophenone (a methyl ketone) is treated with aqueous NaOH and I2 to produce sodium benzoate and iodoform. The yellow precipitate confirms the presence of the methyl ketone moiety in acetophenone.

What does NaOH and br2 do?

Mechanism. The reaction of bromine with sodium hydroxide forms sodium hypobromite in situ, which transforms the primary amide into an intermediate isocyanate. The isocyanate adds water in a nucleophilic addition step to yield a carbamic acid (aka urethane).

Which of the following compound is formed when acetophenone is treated with bromine in acetic acid?

When acetophenone is treated with bromine in the acidic medium it leads to the formation of a compound called m-Bromoacetophenone.

What is the reaction of acetophenone?

Acetophenone oxime reacts with ethylmagnesium bromide to give the dihydro-1,2-oxazine (118) and this with nitrous acid affords 3,5-diphenyl-6H-1,2-oxazine (119).

What is the oxidation product of acetophenone?

Thus, oxidation of acetophenone gives rise to benzoic acid.

How is Triiodomethane formed?

When Iodine and sodium hydroxide are added to a compound that contains either a methyl ketone or a secondary alcohol with a methyl group in the alpha position, a pale yellow precipitate of iodoform or triiodomethane is formed.

Which compound gives ethanamine on reaction with Br2 and Koh?

1-amino propanone is reacted with bromine in presence of potassium hydroxide, Hofmann bromamide reaction takes place which gives ethylamine as a product.

What happens when Br2 reacts with hot and conc NaOH?

a Br2 reacts with hot and strong NaOH solution to give NaBr and H2O.

How is acetophenone formed?

The compound can be synthesized from benzene and acetyl chloride, but it is prepared commercially by the air oxidation of ethylbenzene.

What is the reduction product of acetophenone?

Reduction of Acetophenone to 1-Phyenylethanol.

How benzoic acid is formed from acetophenone?

The \[-C{{H}_{3}}CO\] group is present in acetophenone, when it reacts with iodine in presence of an alkaline medium, the group gets converted to carboxylate ion. On acid hydrolysis, this carboxylate ion gives benzoic acid as the product.

What is the reaction between acetophenone and BR and NaOH?

Acetophenone is a methyl ketone. The addition of Br and NaOH sets up the conditions for the haloform reaction. This reaction turns a methyl ketone into haloform and an acid (or its conjugate base). In this case, the following reaction would occur: I’ve taken some liberties…

What happens when you add Br2 and NaOH to methyl ketone?

The addition of Br 2 and NaOH sets up the conditions for the haloform reaction. This reaction turns a methyl ketone into haloform and an acid (or its conjugate base). In this case, the following reaction would occur: I’ve taken some liberties with this reaction.

How many NaOH and Br2 are needed to make benzoic acid?

It takes three NaOH and Br2 molecules to do this reaction and the product is almost certainly the benzoate ion rather than benzoic acid itself. Most often, the solution is acidified with HCl to produce the final benzoic acid product. What happens when benzaldehyde reacts with acetone in the presence of diluted NaOH?

What happens when nitronium nitrate reacts with benzene?

The nitronium ion reacts with benzene to form the sigma complex, which then loses a proton to generate the aromatic product. Sulfonation of Benzene Benzene will react with sulfur trioxide, and in the presence of an acid, aryl sulfonic acidsare produced. Sulfur trioxide is very reactive electrophile which will sulfonate benzene.
