An aromatic group is a functional group which gives a positive test in a xanthoproteic test.
Xanthoproteic is a test for protein detention. The concentrated nitric acid reacts with proteins if they are present to form yellow colour. By adding alkali it turns orange-yellow through xanthoproteic reaction. Due to a phenyl group, the hydroxyl group can make the test positive in xanthoproteic.
