Question

Aldehydes are the product of oxidation of:

Answer 1

Carboxylic acid : RCHO(aldehyde) --> RCOOH (carboxylic acid).

Answer 2

Answer : An aldehydes are the product of oxidation of primary alcohol.

Explanation :

As we know that the primary alcohols are converted into aldehydes and water via oxidation.

In the terms of organic chemistry we can say that the,

Oxidation takes place by the loss of hydrogen ion or gain of oxygen or loss of electrons.

Reduction takes place by the gain of hydrogen ion or loss of oxygen or gain of electrons.

In the oxidation of primary alcohol, the oxidizing agent removes the hydrogen from the alcohol and forms an aldehyde. The oxidizing agent is represented as [O] in the reaction.

For example :

$CH_3-CH_2-CH_2-OH\overset{[O]}\rightarrow CH_3-CH_2-HC=O+H_2O$

Hence, from the above information we conclude that an aldehydes are the product of oxidation of primary alcohol.
