The Boiling Points of Aldehydes and Ketones Since there is no hydrogen on the carbonyl oxygen aldehydes and ketones do not form hydrogen bonds with themselves Aldehydes and ketones therefore have boiling points that are in between those of alcohols and hydrocarbons of the same molecular weight:

24-Dinitrophenylhydrazine : Aldehydes and ketones react with 24-dinitrophenylhydrazine reagent to form yellow orange or reddish-orange precipitates whereas alcohols do not react Formation of a precipitate therefore indicates the presence of an aldehyde or ketone The precipitate from this test also serves as a solid derivative

share the carbonyl group aldehydes and ketones share much of their chemistry but they are different enough to be considered different classes of compounds This situation is similar to that of alcohols and phenols which both share the -OH group Aldehydes and ketones both undergo a reaction type known as nucleophilic addition
How to identify aldehydes and ketones?
- The two tests that can be used for the identification of aldehydes and ketones are: Aldehydes and ketones react with the reagent 2,4-Dinitrophenyl Hydrazine to give a yellow-orange precipitate. Dissolve the compound in ethanol. To this add alcoholic 2,4-Dinitrophenyl Hydrazine. Shake this reaction mixture well.
What reactions can be used to classify ketones?
- 9.17 KETONES Many of the same reactions that are described above (Section 9.4, pp. 276--286) in the classification of aldehydes can also be used to classify ketones. The addition of 2,4 dinitrophenylhydrazine to ketones to precipitate the 2,4-dinitrophenylhydrazones (Experiment 12, p. 278) is probably the most useful of these reactions. -o- N0 °II
How do aldehydes and ketones react with 2-dinitrophenylhydrazine?
- Aldehydes and ketones react with 2,4-dinitrophenylhydrazine reagent to form yellow, orange, or reddish-orange precipitates, whereas alcohols do not react. Formation of a precipitate therefore indicates the presence of an aldehyde or ketone. The precipitate from this test also serves as a solid derivative.
Do aldehydes react with alcohols?
- Aldehydes and ketones react with 2,4-dinitrophenylhydrazine reagent to form yellow, orange, or reddish-orange precipitates, whereas alcohols do not react. Formation of a precipitate therefore indicates the presence of an aldehyde or ketone. The precipitate from this test also serves as a solid derivative.
