In this contribution, a mild and efficient … WebDec 5, 2014 · You can think of it in terms of, if there is little or no conjugation, the electrons are firmly based in the $\ce{C=O}$ bond. As soon as we introduce some resonance structure, or conjugation, now those electrons can delocalise over 3-4 atoms or even more. This weakens the $\ce{C=O}$ bond, moving the IR peak down to lower wavenumbers.

WebFor a generic ketone (or aldehyde) you can draw a resonance form where the electrons in the double bond move out onto the oxygen. This gives you a structure where there is a positive charge on the carbonyl carbon and a negative charge on the carbonyl oxygen. This form is a minor contributor to the overall (hybrid) structure.
