Question

Write down the chemical test to distinguish between ethane and ethene. Write

reaction involved also.​

Answer 1

You can distinguish ethane from ethene by adding a drop of bromine water to both samples. One will turn from brown to colorless (ethene). The bromine adds to the C-C double bond in ethene in an addition reaction and gets used up so the color goes away.

Answer 2

Answer:

You can distinguish ethane from ethene by adding a drop of bromine water to both samples. One will turn from brown to colorless (ethene). The bromine adds to the C-C double bond in ethene in an addition reaction and gets used up so the color goes away.

EQUATION:-

• CH₃ - CH₃ + Br₂ → no reaction
• CH₂ =CH₂ + Br₂ → CH₂(Br) - CH₂(Br)
