cyclohexane, cyclohexene bromine water (1 Viewer)

Initially what are the colours for cyclohexane, ene and bromine water.

And when u add cyclohexene to the br water, the br water decolourises. Does the cyclohexene also decolourises? ?? ?

cyclohexane - colourless
cyclohexene -colourless

bromine water - brown or yellow depending on how much bromide/bromine(i cant remember the difference..) is in it..

This is what happens in my head:
Br destroys the double bond.. which is cyclohexene resulting in decolourisation. TWO COLOURLESS LAYERS
and for cyclohexane.. nothing happens..pale yellow layer on top and colourless layer at the bottom..

I would advise you to remember this cause its pretty commonly tested...


NOTE THAT I MAYBE WRONG.. but i'm pretty sure i'm right..

You're right. But, left in sunlight the cyclohexane would most probably react, due to the presence of UV rays.

So yeah, it's the bromine water that decolourises, and not the cyclohexene.
