Chemistry 2004 JAMB Past Questions - Question 44: Which of these reagents can confirm the presence of a triple bond?
Choose the correct answers from the options given.
A:
B:
C:
D:
Correct Answer
D
Explanation
The reagent that can confirm the presence of a triple bond is bromine gas (Br2). Triple bonds are highly reactive and can readily react with bromine gas, causing decolorization of the bromine solution. This reaction is known as the bromine test for unsaturation.
In contrast, bromine water is commonly used to test for the presence of double bonds, acidified KMnO4 (potassium permanganate) is also used for the detection of unsaturation but is more specific to double bonds, and copper (I) chloride is not typically used to confirm the presence of triple bonds.
