Questions and Problems 01 Indicate the test results for each of the following compounds in the iodoform test and in the Benedict's test: Idoform Test Benedict's Test CH3 -C- CH2 - CH3 CH3-C-H CH3 -CH2-C-- CH2 - CH3 CH3-C-CH2-C-H

Answer 1

Solution:

1) The iodoform test is given by carbonyl compounds which contains methyl (CH3) group directly attached to C=O functional group.

Hence, compounds 1 ,2 and 4 give positive iodoform test. While compound 3 does not give iodoform test.

2) Benedict's test is given by aldehydes. Ketone do not give positive benedict's test.

Hence, compounds 2 and 3 give positive benedict's test, while compound 1 and 4 do not give positive test.
