The key difference between aldehyde and ketone is that the functional group of an aldehyde occurs always at a terminus whereas the functional group of a ketone always occurs in the middle of a molecule. Aldehydes and ketones are organic molecules with a carbonyl group. In a carbonyl group, carbon atom has a double bond to oxygen.

Aldehydes 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.

Hydroxyl Functional Group; Aldehyde Functional Group; Keton funktionell grupp; Amine En aldehyd kan existera som antingen keto- eller enoltautomer.

For example, the Robinson annulation reaction sequence features an aldol condensation; the Wieland–Miescher ketone product is an important starting material for many organic syntheses. Aldol condensations are also commonly discussed in university level organic chemistry Aldehyd og keton. R betegner et C-atom, som er en del af en større gruppe (kaldes et radikal). Man ser, at forskellen mellem de to grupper er, at H-atomet i aldehydgruppen er erstattet med en R-gruppe i ketonen.

En aldehyd är en organisk förening som innehåller en aldehydgrupp (även kallad formylgrupp). Denna grupp består av en kolatom med dubbelbindning till en syreatom och en väteatom. Gruppen betecknas vanligen -CHO. Den liknar, men är inte samma som ,-OH, som är en alkoholgrupp.

Aldehyde und Ketone sind Moleküle mit einer funktionellen Carbonylgruppe (=O) . Bei Aldehyden ist, im Gegensatz zu den Ketonen, am

Oxidation av Ketoner skiljs från andra ämnesklasser med karbonylgrupper, som karboxylsyror, aldehyder och estrar, genom att deras karbonylgrupp är bunden till två kolatomer. De skiljer sig från alkoholer och etrar genom att syreatomen är dubbelbunden till sin kolatom. Den minsta ketonen är aceton (propanon). Aldehyde considered an organic compound containing the general chemical formula R-CHO, while ketone is considered an organic compound containing the general chemical formula R-CO-R ’.

Sugars With Free Aldehyde Or Ketone Groups Are Called. BSC2010L Figure 2.1:Glucose and fructose are both monosaccharides as well as structural isomers.

Hier die Reaktionsmechanismen und Reaktionsgleichungen dazu.Das Video zu den Grundlagen der Alkohole An aldol or aldol adduct is a hydroxy ketone or aldehyde, and is the product of aldol addition (as opposed to aldol condensation, which produces an α,β-unsaturated carbonyl moiety).When used alone, the term "aldol" may refer to the specific aldol, 3-hydroxybutanal. Discovery. The aldol reaction was discovered in 1872 by French chemist Charles-Adolphe Wurtz, and has remained a staple in Aldehyde and Ketone reduction by LiAlH 4 to Alcohols. LiAlH 4 is a strong reduction reagent used in organic chemistry. LiAlH 4 can reduce aldehyde and ketone to alcohols. When aldehyde is reduced by LiAlH 4, primary alcohol is given as the product.But, reduction of ketone will give a secondary alcohol.
