Q: Which reagent can be used to distinguish between an alkyne and an alkene?
Solution:
Bromine water can be used to distinguish between an alkyne and an alkene, as alkynes will decolorize it.
Steps: 5
Show Steps
Step 1: Understand that alkenes and alkynes are types of hydrocarbons. Alkenes have a double bond, while alkynes have a triple bond.
Step 2: Know that bromine water is a reddish-brown solution used in chemical tests.
Step 3: Add bromine water to the sample you want to test (the alkyne or alkene).
Step 4: Observe the color change. If the solution turns colorless, it means the compound is an alkyne.
Step 5: If the solution remains reddish-brown, the compound is an alkene.
