TESTS FOR FUNCTIONAL GROUPS IN ORGANIC COMPOUNDS. 87. Material Required ORGANIC COMPOUNDS. 93. These two carbonyl compounds (aldehydes and ketones) are.
Addition reactions to aldehydes and ketones using Grignard reagents are among the most important reactions in organic synthesis. • These reactions are carbon-

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

Tollens’ Test: Aldehydes are oxidized to carboxylic acids in the presence of Ag(I) The silver byproduct from this reaction leaves a shiny silver mirror on the walls of the flask OAg+O Ag (Mirror) HNH3H2OOH Be sure to use a new test-tube for this reaction To the test-tube add 1 mL of 5 AgNO3

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
