Give two chemical tests to detect unsaturation in organic compounds.
Answer»
Bromine test: When 5% solution of bromine in carbon tetrachloride is added to an alkene, it gets decolourized. This Indicate the presence of unsaturation in organic compound.
Bayer’s test: When alkene is oxidised with cold,. alkaline KMnO4, diol is formed. The KMnO4 gets decolourized. This indicates the presence of unsaturation of organic compound.
