The reduction of ketone groups, such as those present on coq, produces alcohols. in contrast, oxidation of aldehydes produces wh
nevsk [136]

On oxidation of aldehydes produces carboxylic acid functional group.

The product of oxidation of aldehydes depends upon whether the reaction occur in acidic medium or alkaline condition.

If oxidation of aldehydes occurs under acidic condition the product is carboxylic acid but if oxidation of aldehydes occurs under alkaline condition then reduce as well as oxidized product obtained which is known as disproportional product.

The  oxidation of aldehydes occur through potassium dichromate, potassium permanganate or many more. The oxidation of aldehydes in the presence of base is known as cannizzaro's reaction.

The bond between which two atoms has the greatest degree of polarity
Alenkasestr [34]

Answer:

By comparing  the bonds between C-H and O-H, the O-H bond has the greatest degree of polarity.

Explanation:

Based on bond electronegative values which is a measure of the ability of a atom in a chemical bond to pull the shared electrons closer to its self.

The electronegativity of an element characterizes the elements chemical reaction.

From the available bonds

Oxygen has an electronegativity value of 3.44 and Carbon 2.55, while  Hydrogen has an electronegativity value of  2.20

Therefore the bond between carbon and hydrogen is much less polar than between oxygen and hydrogen.

The bond between oxygen and hydrogen has the greatest polarity.
