No, bromine will only add to alkenes, so NO addition reaction to alkanes. Subtitution on alkanes is not possible at standard conditions
If this is supposed to be an alkene test, then no, hexane will not react with bromine water to take away its color as it is an alkane and therefore contains no double bonds. But bromine water will react with sodium hydroxide; bromine water contains either HCl or H2SO4, both of which will of course react with sodium hydroxide. In addition, I believe (from some experiments like this that I've done recently) that sodium hydroxide will actually react with the free bromine in the bromine water, as evidenced by the change in color from the orange-ish color of bromine water to a pale yellow.
As polyehtene is unsaturated(single bond) it does not react with bromine and there is no colour change.But bromine reacts with ethene and it becomes colourless.
Yes, however it doesn't require it either to react. ethene+bromine water→1,2-dibromoethane Ethane reacts with bromine only in the presence of UV forming bromoethane and hydrogen bromide.
When aluminum and bromine react, three bromine atoms combine with each aluminum atom.
With bromine, it gives the dibromide.
Bromine water can test the difference between alkanes and alkenes because the bromine water turns colourless for the alkenes but doesnt change for the alkanes.
no
When grignard reagents react with water, they create alkanes. In order for alkanes to successfully be produced, everything in the area must be completely dry.
Organic compounds called Alkenes turns Bromine to colourless from orange-ish without sunlight as a catalyst. Alkanes however require sunlight to react.

Alkenes have a double bond between the carbon atoms (C=C) whereas alkanes have a single bond (C-C). so alkenes are unsaturated compounds, add aqueous solution of Bromine or KMnO4 to both the compounds the decolourization of these reagents confirms the presence of alkenes.

I think it's because the covalent bonds are strong, and therefore unreactive to acids & alkalis. You'd need to get alkanes in gas form to make it react, but you'd still need energy for it to react, like, say, heat perhaps?
by adding bromine water to the compound. if it is unsaturated, the red colour of the bromine water will fade quickly. if it is saturated, then it will not fade.
Bromine, which is represented by the chemical symbol Br, is very corrosive with most other elements. The only element I could find it does not react with is water.
