For this experiment the possible categories of the unknown are alkane
indicative of an aldehyde or ketone but only that such a group is present. Test 2: Tollen's Test. This test is selective for aldehydes. It is based on the

Aldehyde resin turns dark-brown to purple after a 5 min reaction followed by a 10 min air oxidation period. Resins that possess other functional groups (i.e.
Carbohydrates are a class of natural compounds that contain either an aldehyde or a ketone group and many hydroxyl groups – they are often called polyhydroxy.
The Fehling test was developed in 1848 by Herrmann Feh- ling. It is a indicating reaction for reducing groups such as aldehyde functions.
If this test is positive perform the following test to distinguish between aldehyde and ketone. a) Test for nitro group – 0.2 gm of the compd. + 2 ml of ...

TESTS FOR FUNCTIONAL GROUPS IN ORGANIC COMPOUNDS. 87. Material Required. • Test tubes attached to the carbon atom adjacent to carbonyl group by iodine.
indicative of an aldehyde or ketone but only that such a group is present. Test 2: Tollen's Test. This test is selective for aldehydes.
In this experiment we will test for the carbonyl group. This can be investigated using 2
numbering starts from the end with the aldehyde. - methyl group is therefore on 4th carbon. 4-methylpentanal. The simplest aromatic aldehyde and ketone are:.
Structures of unknown compounds can be determined by comparing physical properties performing functional group tests
