How are aldehydes and ketones different
Did you know?
WebAldehydes and ketones are organic compounds which incorporate a carbonyl functional group, C=O. The carbon atom of this group has two remaining bonds that may be occupied by hydrogen or alkyl or aryl substituents. If at least one of these substituents is hydrogen, the compound is an aldehyde. If neither is hydrogen, the compound is a ketone. Web25 de jul. de 2024 · They differ greatly, however, in one most important type of reaction: oxidation.

WebThe difference between carboxylic acid derivatives and aldehydes and ketones is that there is a group containing a negatively charged heteroatom (usually oxygen, nitrogen or sulfur), which is directly connected to the carbonyl carbon atom. You can think of carboxylic acid derivatives as bilateral. Web8 de abr. de 2024 · In addition, the increase of the total content of ketones and aldehydes mainly occurs at higher temperatures, because lignin decomposes more completely at high temperatures to produce more ketones and aldehydes. The influence of PS on the contents of bio-oil components occurs only in a small range (Shen et al., 2009).
