ncert.nic.in365 Aldehydes, Ketones and Carboxylic Acids The physical properties of aldehydes and ketones are described as follows. Methanal is a gas at room temperature. Ethanal is a volatile liquid. Other aldehydes and ketones are liquid or solid at room temperature. The boiling points of aldehydes and ketones are higher than

ncert.nic.inBoth aldehydes and ketones contain carbonyl group (>C = O) and are commonly known as carbonyl compounds. Identification of aldehydes and ketones is done by two important reactions of carbonyl group i.e. (i) addition reaction on double bond of >C = O group and (ii) oxidation of carbonyl group. Addition reactions of derivatives of ammonia are ...

people.chem.umass.edu2,4-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.

crab.rutgers.eduCh18 Ketones and Aldehydes (landscape) Page 15 Reactions of Aldehydes and Ketones The most common reaction of aldehydes and ketones is nucleophilic addition. This is usually the addition of a nucleophile and a proton across the C=O double bond. As the nucleophile attacks the carbonyl group, the carbon atom changes from sp2 to sp3.
