WebAnswer 2. In the given reaction ketone has an acidic …. by removing a hydrogen atom on the a carbon atom. While Figure 1 uses a ketone as the nucleophile and an aldehyde as the electrophile, both ketones and aldehydes can act as the nucleophile or electrophile. aldehyde is important. This identification will be done using IR spectroscopy. WebWe have a higher frequency of vibration, we get a higher wave number. So the signal for this carbonyl appears at a higher wave number, so approximately 1800, or even a little bit higher than that, so 1815 or so. So once again, that's the approximate value for the signal of the carbonyl for an acyl or acid chloride.
WebJul 20, 2014 · Both aldehydes and ketones contain the carbonyl group, C=O, and are often called carbonyl compounds. An aldehyde is often written as RCHO. Remember that the H atom is bonded to the carbon atom, not the oxygen. • Likewise, a ketone is written as RCOR, or if both alkyl groups are the same, R2CO.
