Is it easier to oxidize an alcohol or an aldehyde?

Answer 1

The oxidation product of an aldehyde will depend on whether the conditions are acidic or alkaline. The aldehyde will oxidize to a carboxylic acid if it is acidic. If it is alkaline, the aldehyde will form a salt because the acid would react.

Answer 2

The oxidation fo an aldehyde converts it into carboxylic acid, for example when Acetaldehyde is oxidized with the help of Potassium dichromate in presence of Sulphuric acid the Acetic acid is formed.

CH3-CHO + [O] = CH3-COOH

It can be oxidized using reagents such as DIBAH (Diisobutyl aluminum hydride), or with KMnO4 (potassium permanganate). KMnO4 can actually even oxidize a methyl group completely to a carboxylic acid. DIBAH can only oxidize an aldehyde to a carboxylic acid.

Answer 3

It is easier to oxidize an alcohol than an aldehyde because alcohols can be oxidized to form aldehydes or further to carboxylic acids. Aldehydes are already partially oxidized so they are more stable and less reactive towards further oxidation.

Answer 4

Aldehyde can be oxidized by acidified KMnO4(aq) or acidified K2Cr2O7(aq) to give carboxylic acid.

For example,

RHC=O + acidified KMnO4 or K2Cr2O7 --------> RHOC=O

Answer 5

One way to produce an aldehyde is to react a terminal alkyne with BH3 (borane) and than treat it with H2O2 (hydrogen peroxide) and -OH(hydroxide).

Answer 6

Aldehydes are easily oxidize to carboxylic acids.

Answer 7

Oxidation of acealdehyde (CH3CHO) will yield acetic acid (CH3COOH).

Answer 8

ALDEHYDE
