A hydrocarbon decolourizes `KMnO_5` solution but does not form any precipitate with either ammoniacal `AgNO_3 or Cu_2Cl_2`.
What will be the change on adding a few drops of bromine solution to a test tube filled with this hydrocarbon?

Text Solution

AI Generated Solution

To solve the problem, we need to analyze the behavior of the hydrocarbon in question when it interacts with different reagents. ### Step-by-Step Solution: 1. **Identify the Hydrocarbon Type**: - The hydrocarbon decolorizes KMnO4 solution. This indicates that it is likely an unsaturated hydrocarbon, either an alkene or an alkyne, since alkanes do not react with KMnO4. - The hydrocarbon does not form any precipitate with ammoniacal AgNO3 or Cu2Cl2. This suggests that it is not a terminal alkyne, as terminal alkynes would react with these reagents to form precipitates. ...
