Organic Chemistry Resonance Practice - Resonance of Ketones and Esters (Carbonyls)

Resonance forms of carbonyl containing molecules are extremely important concepts in organic chemistry. This video will go over the resonance of a ketone and an ester. If you are able to draw the correct resonance forms of an carbonly containing compounds you can predict the reactivity of a molecule by knowing where an partial negative (delta negative) and partial positive (delta positive) are located on a molecule.

Resonance involves arrow pushing. Arrow pushing involves the movement of electrons. For resonance arrow pushing involves the pi electrons only. It is very important that you become skilled at pushing arrows for resonance as it will be a valuable skill when you move into mechanisms.

I recommend that you download the problem from the link below and attempt the problem yourself and use this video to correct your work.
