How would you explain the structural difference between a aldehyde, ketone, carboxylic acid, and an ester?

Each varies from the others by the way the oxygens are linked to the carbon atoms.

Explanation:

The carboxylic acid ends with a carbon attached by a double bond and a single bond to and oxygen and a hydroxyl (OH) group, respectively.

An ester is like a carboxylic acid, except that it has another carbon group attached to one oxygen instead of a hydrogen.

Aldehydes are like the acids, except that they have a terminal hydrogen instead of the hydroxyl group.

The ketones are to the aldehydes as the esters are to the acids – they have the same double-bonded oxygen, but instead of a terminal hydrogen there are additional C-H units.
