Why the brown color of bromine disappear when mixed with cyclohexene?

Halogens react with alkenes to form haloalkanes. Addition of the bromine in this case occurs across the double bond in cyclohexene. The resultant products are colourless hence the brown colour disappears.

What is the color of gaseous bromine?
Kind of Red/Brown, or rust color, but vibrant.
What changes in color when bromine reacts with an alkyne?
It changes from brown to colorless. Br2 has a brown color before it reacts with the alkene, forming a dibromoalkane as the alkene opens up its double bond and bromine joins up with that bond. The Br-Br bond is broken, hence removing the brown color. In reality, the appearance of bromine water depends on its concentration.
Is bromine a metal?
Bromine is not a metal. It is a nonmetal halogen and is the inly nonmetal that is liquid at room temperature. Its chemical symbol is Br and has an atomic number of 35. It is reddish-brown in color with a metallic luster (even though it is not a metal).
What is the chemical formula for bromine gas?
What happens to bromine gas in a sealed tube when it is cooled and later heatedAnswer:When bromine is cooled and then heated in a sealed container, the bromine juice starts evolving in a gaseous state. It then becomes a gas i.e. bromine gas which is red-brown in color
What halogen and is a red liquid at room temperature?
Sounds like bromine. (It actually is.) Bromine is also volatile. A link is provided below.Yes that is correct but say if this quest was in an exam, you wouldn't write that.The answer is Bromine because the question clearly states, at room temperature this halogen is a liquid,and on any periodic table, bromine is a different colour to the other elements showing that it is a liquid or it melts close to room temperature. Bromine, Mercury, Gallium, Ceasium and Francium are all the same colour as each other. Also, yes. Bromine is volatile.Hope this helps! :)

Why should excess bromine water be avoided in the test for free tryptophan?
The presence of excess bromine water will cause the pink color to disappear and it may be masked by the color of the reagent.
What does bromine look like in its color in natural state?
It is a redish brown color.

How do some gases have a color?
fluorine, chlorine, bromine, all are coloured. fluorine is pale yellow, chlorine is greenish, and bromine is reddish brown. these three make up the first three halogens in the 7th group of the periodic table.
What happens when the bromine solution is first added to cyclohexane?
At room temperature, the halogens like bromine don't react with cyclohexane. Hence the dark brown color of the bromine water remains. When heated, the -H atoms are replaced with -Br(substitution reaction).
