Add Bromine water (Br2) which is red/orange/brown in colour.The Hex-1-ene will decolorise the bromine water to colourless.
The Cyclohexane will NOT decolorise bromine water. It will remain red/orange in colour.
NB
This is the classic test for Alkenes.

In darkness, add separately bromine solution to hex-1-ene and cyclohexane.
When added to hex-1-ene, the orange bromine solution turns colorless.
CH₃CH₂CH₂CH₂CH=CH₂ + Br₂ →CH₃CH₂CH₂CH₂CHBrCH₂Br
When bromine solution is added to cyclohexane in darkness, there is no observable change.

No need to do it in the dark.
