because it has two oxygen atoms

There is a carbonyl chapter in every organic chemistry textbook that will cover this in detail

I do not think it specificall answer on my question. It just says which reactions are possible with normal ketones and which with esters.

A lot of reactions are posible with ketones, but not whith ester, why?

What about aldehydes? And carboxylic acids? Or acyl halides?

Why are they different? They all have a C=O group.

Aldehyde react a lot similar like ketones.  On the other hand acid and acid derivatives usualy react similar to esters.

Perhaps we should ask this question. Why are amide less reactive than esters and less reactive than anhydrides and less reactive than acyl chlorides? If you have succeeded in answering why amides are the least reactive than esters, then you may answer why esters are less reactive than ketones.
