Hi I was wondering if anyone could help me with this question:

Describe how you would carry out a lab test to compare the reactivity of liquid 1-heptene with liquid heptane.

Thanks in advance!

add some drops of bromine water. the more reactive liquid will react with the bromine and discolour (assuming u meant 1-heptene) while the less reactive liquid (heptane) will not discolour.

1-haptane and haptane are they same thing.. that has to be 1-haptene

lolz, yea, kz...

then, wif the absense of ultraviolet radiation, only 1-heptene will discolor the brown bromine water (addition may occur, hence 1-heptene) while at the presense of ultraviolet radiation, both 1-heptene and heptane will discolor the bromine water (BOTH addition and substitution may occur)... but empirically, i fink 1-heptene will discolor the bromine water at a faster rate...
