What colour is bromide gas?
Bromine is a liquid at room temperature, but after 58,8 0C bromine become a gas.
What is the chemical symbol for stable bromine?
The chemical symbol for the element bromine is Br. The elemental form of bromine is theoretically in the diatomic form (Br2), but it is not found in that form freely. Most of the bromine on earth exist as bromide salts in crustal rock.Chemical symbol for stable bromine is Br2. The state of matter of it is liquid. It is red-brown in colour.
How bromine is used to test for unsaturation in organic compounds?
Bromine is used as a reagent to test for unsaturation in organic compounds due to its ability to react with alkenes and alkynes, which contain carbon-carbon double or triple bonds. When bromine is added to a saturated compound, no reaction occurs, and the reddish-brown color of bromine persists. However, if the compound is unsaturated, bromine will react with the double or triple bonds, resulting in a color change as the reddish-brown color disappears. This decolorization indicates the presence of unsaturation in the organic compound.
Which element is a brown liquid poisonous diatomic molecule at room temperature?
Bromine (Br2) is a brown liquid poisonous diatomic molecule at room temperature.
What is the element with the symbol BR?
Bromine is a non metal. atomic number of it is 35.
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 colour of the bromine with the cyclohexene?
Bromine is reddish-brown in color. When it reacts with cyclohexene, the solution initially turns from red to colorless as the bromine adds across the double bond, forming a dibromo compound.
What short chemical test could you make on the product to indicate whether cyclohexene is present or absent?
One simple test to determine the presence of cyclohexene would be to perform a bromine water test. Add a few drops of bromine water to the product; if cyclohexene is present, the red-brown color of the bromine water will disappear due to addition reaction with the cyclohexene. If the color remains, it indicates that cyclohexene is absent.
Is bromine gas red?
It is a reddish-brown colour.
Equation of cyclohexene and bromine water?
When cyclohexene reacts with bromine water, the bromine molecule adds across the C=C double bond to form a dibromide product. The reaction is a test for the presence of carbon-carbon double bonds (alkenes), as the reddish-brown color of bromine water decolorizes upon addition to an alkene due to the formation of the colorless dibromide product.
What is the color of gaseous bromine?

What color is bromine water?
Bromine water is a reddish-brown color.
What is the color of metal bromine?

What colour is the solid of bromine?
The solid form of bromine is a reddish-brown color.
What is the Colour and physical state of bromine at room temperature?
Bromine is a reddish-brown liquid at room temperature.
What colour is bromine dissolved in cyclohexane?
Bromine dissolved in cyclohexane appears orange in color.
