Types of Organic Reactions- Bromination of Saturated and Unsaturated Hydrocarbons

Bromination of Saturated and Unsaturated Hydrocarbons

Description: A solution of bromine in carbon tetrachloride is added to both pentane and pentene. The pentene decolorizes immediately; the pentane takes longer. The pentane decolorization can be hastened by a bright light. Addition of bromine to benzene will not decolorize.
