Does CH3CH Oh CH3 give iodoform test?

Any compounds containing the CH3C=O. group or the CH3CH(OH) group give a positive result with the iodoform test.

Which alcohol does not respond to iodoform test?

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.

Which element does not give iodoform test?

attached to the carbon, Acetophenone gives the iodoform test. group in which electrons are delocalised, hence, it also does not give the iodoform test.

Can acetaldehyde give iodoform test?

– There are two different ways in which we can perform the iodoform reaction. One is by using iodine and sodium hydroxide solution and the other one is by using potassium iodide and sodium hypochlorite solutions. Hence ethanal or acetaldehyde (CH3CHO) is the only compound among options that gives iodoform reaction.

Does Butanal give iodoform test?

Complete answer: No, butanal doesn’t give a positive iodoform test. The solitary aldehyde that gives a positive iodoform test is acetaldehyde.

Does isopropyl alcohol give iodoform test?

Yes, isopropyl alcohol gives a positive iodoform test.

Which organic compounds give iodoform test?

Ethanal is the only aldehyde to give the triiodomethane (iodoform) reaction. If “R”is a hydrocarbon group, then you have a ketone. Lots of ketones give this reaction, but those that do all have a methyl group on one side of the carbon-oxygen double bond. These are known as methyl ketones.

Will benzyl alcohol give iodoform test?

Benzyl alcohol PhCH2OH has no keto methyl group and being a 1-degree alcohol, will not respond to Iodoform test. Hence, negative iodoform test is given by Benzyl alcohol.

Does Hcooh give iodoform test?

No. The reason being that carboxylic acid and its derivatives do not give iodoform test.

Does propanone give iodoform test?

(i) Propanone gives iodoform test while propanol does not give this test. (ii) Benzaldehyde (C6H5CHO) and acetophenone (C6H5COCH3) can be distinguished by iodoform test. Acetophenone, being a methyl ketone on treatment with I2/NaOH undergoes iodoform reaction to give a yellow ppt.

Does acetaldehyde give Fehling test?

Acetaldehyde reduces Fehling’s solution but benzaldehyde does not.
