pKa data for various systems, active methylene compound acidity. Why are the protons adjacent to carbonyl groups acidic? As we have advocated before, look. However, this does not imply that vCO is essentially a diatomic vibration, as this result is . through a comparison of vCO values in fulvenic ketones with bond indices pKa values of the free acids, and similar results have been reported for.
We can form ketones, aldehydes, and carboxylic acids by oxidation of alcohols.
