Does ethyl methyl ketone give Haloform test?

Acetaldehyde is only aldehyde that gives positive haloform test. Ethyl alcohol is the only primary alcohol that gives positive haloform test. When methyl ketones are treated with sodium hydroxide and iodine, yellow precipitate of iodoform is produced which indicates positive haloform test.

Why do only methyl ketones form an Haloform?

Question: Why do only methyl ketones form a haloform? The haloform reaction requires that a group be created that is a stronger base than hydroxide ion For an alkyl group to be the stronger base, the alpha-carbon must be bonded to three halogen atoms.

Which ketone does not give haloform reaction?

The name of the compound is Methyl ethyl ketone. This compound does not have 3 alpha Hydrogen atoms and does not fulfil the criteria for the haloform reaction.

Do ketones give Haloform test?

When the halogen used is iodine, the haloform reaction can be used to identify methyl ketones because iodoform is a yellow solid with a characteristic odor. The test is known as the iodoform test.

Why does ethanol give a positive iodoform test?

Ethanol is the only primary alcohol to give the triiodomethane (iodoform) reaction. No tertiary alcohols can contain this group because no tertiary alcohols can have a hydrogen atom attached to the carbon with the -OH group. No tertiary alcohols give the triiodomethane (iodoform) reaction.

Why does methyl acetate does not give iodoform test?

The reason being that carboxylic acid and its derivatives do not give iodoform test. This is because due to resonance there is no free existence of C=O. group which is required for reaction. Iodoform test is shown only by carbonyl compounds ( Aldehyde and Ketones) which have Methyl group ( CH3 – ) on the α position.

Why is the bromoform reaction of methyl ketones performed under basic but not acidic reaction conditions?

After halogenation of its enolate, the resulting dihalo ketone is in turn even more acidic than its two precursors (thanks to the two electron-withdrawing groups on the alpha carbon) which means it will out-compete these ketones for base.

Which compound does not give haloform reaction?

Acetic acid does not undergo haloform reaction.

Which of the following compound gives ethyl methyl ketone on oxidation?

Therefore, we can see that $2 – bu\tan ol$ on oxidation gives ethyl methyl ketone.

Which of the following carbonyl compound does not give haloform reaction?

Benzophenone does not give haloform reaction since it does not contain CH3CO group.
