Which of the following compound is obtained by the oxidation of primary alcohol with nascent oxygen?
Explanation: Ketone compound is obtained by the oxidation of secondary alcohols by nascent oxygen atom [O].
What type of compound is prepared by the oxidation of primary alcohols?
Primary alcohols can be oxidized to form aldehydes and carboxylic acids; secondary alcohols can be oxidized to give ketones.
What will be the product of oxidation of primary alcohol with strong oxidizing agent?
They also oxidize secondary alcohols to ketones. ”Strong” oxidants convert primary alcohols to carboxylic acids. They also oxidize secondary alcohols to ketones. None of the reagents we’ve encountered will oxidize tertiary alcohols.
What is the oxidizing agent that can oxidized both primary and secondary alcohol to form aldehydes and ketones respectively?
PCC oxidizes alcohols one rung up the oxidation ladder, from primary alcohols to aldehydes and from secondary alcohols to ketones.
Which alcohol is most soluble in water?
Because of the strength of the attraction of the OH group, first three alcohols (methanol, ethanol and propanol) are completely miscible. They dissolve in water in any amount.

Alcohol solubility chart.
| Name | Formula | Solubility |
|---|---|---|
| Methanol | CH3OH | miscible |
| Ethanol | C2H5OH | miscible |
| Propanol | C3H7OH | miscible |
| Butanol | C4H9OH | 0.11 |
What is nascent oxygen?
Answer: A very reactive and very unstable monoatomic oxygen is considered nascent oxygen and it is represented as [O]. It is a monatomic element. It has a high tendency to react to obtain an oxygen molecule (O2) with the other [O] nascent oxygen.
What is the difference between primary and secondary alcohols?
A primary alcohol is an alcohol in which the hydroxy group is bonded to a primary carbon atom. It can also be defined as a molecule containing a “–CH2OH” group. In contrast, a secondary alcohol has a formula “–CHROH” and a tertiary alcohol has a formula “–CR2OH”, where “R” indicates a carbon-containing group.
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.
How do primary and secondary alcohols differ?
Alcohols are organic molecules containing a hydroxyl functional group connected to an alkyl or aryl group (ROH). If the hydroxyl carbon only has a single R group, it is known as primary alcohol. If it has two R groups, it is a secondary alcohol, and if it has three R groups, it is a tertiary alcohol.
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.
What is the strongest oxidant?
The strongest oxidant in the table is F2, with a standard electrode potential of 2.87 V. This high value is consistent with the high electronegativity of fluorine and tells us that fluorine has a stronger tendency to accept electrons (it is a stronger oxidant) than any other element.
Which alcohol is resistant to oxidation?
Tertiary alcohols (R3COH) are resistant to oxidation because the carbon atom that carries the OH group does not have a hydrogen atom attached but is instead bonded to other carbon atoms.
Which of the following is not capable of oxidizing a secondary alcohol to a ketone?
Which of the following is not capable of oxidizing a secondary alcohol to a ketone? Explanation: Lithium aluminum hydride is correct because it is a reducing agent, and is therefore not capable of oxidizing secondary alcohols.
Why is oxidation of propanal is easier than propanone?
Oxidation of aldehyde is easier because of the H atom which makes it easy to oxidise whereas in case of ketones there is no H atom so, to oxidise ketones we need strong oxidising agents.
Which alcohol does not give a ketone on oxidation?
Tertiary alcohols having no H on carbon bearing-OH group do not under oxidation reaction under neutral or alkaline conditions.
