You asked: Which of the following alcohols can be oxidized to a ketone?

Chromic acid oxidizes primary alcohols to carboxylic acids, and it oxidizes secondary alcohols to ketones. Tertiary alcohols do not react with chromic acid under mild conditions.

Which alcohols can be oxidized to form a ketone?

Primary alcohols can be oxidized to form aldehydes and carboxylic acids; secondary alcohols can be oxidized to give ketones. Tertiary alcohols, in contrast, cannot be oxidized without breaking the molecule’s C–C bonds.

Which of the following oxidizes to give ketone?

Secondary alcohols are oxidized to ketones by chromic anhydride (CrO3): Tertiary alcohols having no H on carbon bearing-OH group do not under oxidation reaction under neutral or alkaline conditions.

Which alcohol is most readily oxidized?

Primary alcohol gets easily oxidized to an aldehyde and can further be oxidized to carboxylic acids too. Secondary alcohol gets easily oxidized to ketone but further oxidation is not possible. Tertiary alcohol doesn’t get oxidized in the presence of sodium dichromate.

Which alcohol can be oxidised but not dehydrated?

Ethanol is the alcohol that can be oxidised by acidified potassium dichromate but cannot be dehydrated.

Which of the following is ketone?

The simplest ketone is acetone (R = R’ = methyl), with the formula CH3C(O)CH3. Many ketones are of great importance in biology and in industry. Examples include many sugars (ketoses), many steroids (e.g., testosterone), and the solvent acetone.

Can you oxidize a ketone?

Oxidation of Ketones

Because ketones do not have hydrogen atom attached to their carbonyl, they are resistant to oxidation. Only very strong oxidizing agents such as potassium manganate(VII) (potassium permanganate) solution oxidize ketones.

Can 2 propanone be oxidized?

The oxidation of the simplest secondary alcohol, 2-propanol, yields propanone. Tertiary alcohols cannot be oxidized in this way because the carbon to which the hydroxyl group is attached does not have another hydrogen atom attached to it.

Is oxidation of alcohol reversible?

All reactions are reversible under reductive conditions. Selective oxidation of primary alcohols to aldehydes is the most difficult preparation to be carried out. In most cases, further oxidation to carboxylic acid is being observed even under mild conditions and the use of only one equivalent of oxidizing agent.

Which alcohol can be oxidised by acidified potassium dichromate VI but Cannot be dehydrated?

(h) Draw the structure of the isomer of A that cannot be dehydrated to form an alkene by reaction with concentrated sulfuric acid. Ethanol can be oxidised by acidified potassium dichromate(VI) to ethanoic acid in a two-step process.

Which alcohol can be oxidised by k2cr2o7 and h2so4 to form a ketone?

Secondary alcohols are oxidised to ketones – and that’s it. For example, if you heat the secondary alcohol propan-2-ol with sodium or potassium dichromate(VI) solution acidified with dilute sulphuric acid, you get propanone formed.

INFORMATIVE:  How do you reduce a ketone from a secondary alcohol?

Which alcohol is most easily dehydrated?

Which one of the following alcohols undergoes dehydration most easily? The reactivity order for dehydration of alcohols is tertiary alcohol > secondary alcohol > primary alcohol. Therefore, the alcohol, CH3 |CH3CH2-C-CH2CH3 | OH is dehydrated most rapidly.

Can KMNO4 oxidize a tertiary alcohol?

Yes, that’s right. Tertiary alcohols readily undergo elimination to yield alkenes, then the KMNO4 reacts with the alkene to give syn dihydroxylation.
