Answer #1

1. The macromolecule tested in each tube is carbohydrate. For eg., the test tube A contains carbohydrate.This is confirmed by Molisch test. This gives purple colour if there is a carbohydrate in the sample.

2. The sample tested in tube E is a hexose. This test is Bials test. This test is done to find the pentoses in carbohydrate. If the sample contains pentose, then the colour will be blue or green. If the sample contains Hexose sugar, then the colour will be muddy brown grey.
