If a compound has no double bond, bromine water will...

Explanation:
Bromine water is used to test for unsaturation (the presence of carbon–carbon double bonds). Bromine adds across a C=C bond and the orange-brown color of bromine disappears when a reaction occurs. If there is no double bond, no addition reaction can take place, so bromine remains in solution and the color does not change. That’s why a compound with no double bond will keep bromine water the same color.
