Phenol is activated by the OH group, which means it is more readily brominated than benzene. The OH group has an electron supplying effect, the ring is then more electron rich. The lone pair from the oxygen atom is interacting with the ring electrons, thus making the ring more attractive to electrophiles (the electrophile here being Brdelta+) . Compare this with brominating a plain benzene ring where you would need a halogen carrier (Friedel-Crafts type) to generate a strong enough electrophile. It undergoes trisubstitution because phenol is so readily brominated and the bromine goes onto the activated positions on the ring (2,4,6) Hope this is enough information Marie

What is the difference between Bromine liquid and Bromine aqueous solution?
Bromine has only 2 stable isotopes(isotopes which do not undergo radioactive decay), whereas mercury has 7 stable isotopes. Mercury is a heavy weight metal, whereas bromine isn't exactly jusy as heavy. Mercury's atomic weight is200.59, which is heavier than bromines atomic weight of 79.904. Bromine has a strong bleachong action and smells of chlorine whileis obtained mainly from cinnabar, and is toxic to breath or ingest. While bromine does react quite fairly to most acids, mercury does not react with most of the acids known and tested. both of these metals belong to two entirely different groups. One similarity that these two fluid metals share is that they are liquid metals.
What happens when bromine water is added to paraffin?
When bromine water is added to paraffin, no visible reaction occurs. Paraffin is a non-reactive hydrocarbon compound, so it does not undergo a chemical reaction with bromine. The bromine remains as a colored solution with no change in the paraffin.
What is the reaction of ethene with bromine in aqueous solution of sodium chloride?
When ethene reacts with bromine in an aqueous solution of sodium chloride, the bromine adds across the carbon-carbon double bond in ethene through electrophilic addition. This reaction forms a dibromoethane product. The presence of sodium chloride in the aqueous solution helps to generate hypobromous acid, which is the active bromine species that reacts with ethene. This reaction is an example of halogenation of alkenes.
When preforming the bromine test to distinguish between aromatic and alkene compound?
In the bromine test, an alkene compound will decolorize a bromine solution whereas an aromatic compound will not react with the bromine solution. This is because the double bond in the alkene readily reacts with bromine to form a colorless product, while the stable aromatic ring in the aromatic compound does not undergo such reaction.
Aqueous potassium bromide and aqueous calcium acetate in net ionic equation?
there is no net ionic equation. theoretically, there would be a double replacement reaction: 2KBr (aq) + Ca(C2H3O2)2 (aq) --> CaBr2 (aq) + 2KC2H3O2 (aq) however, CaBr2 and KC2H3O2 are both soluble. net ionic equations include only the species that undergo change in an aqueous solution. since all the ions start out as being dissolved in solution, and all the ions end as being dissolved in solution, no ions undergo change, and there is not net ionic equation.

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).
What is the behavior of copper ions in aqueous solution?
Copper ions in aqueous solution tend to form complexes with water molecules, resulting in a blue color. They can also react with other ions in the solution, such as chloride or sulfate, to form insoluble precipitates. Additionally, copper ions can undergo redox reactions, where they can be reduced or oxidized depending on the conditions of the solution.

What are the Chemical equations to distinguish between alkane and alkene?
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.
When an aqueous solution of lead(II) nitrate is mixed with an aqueous solution of sodium iodide an aqueous solution of sodium nitrate and a yellow solid lead iodide are formed.?
Lead(II) nitrate and sodium iodide undergo a double displacement reaction to form sodium nitrate and lead(II) iodide, which is a slightly soluble yellow solid. The balanced chemical equation for this reaction is: Pb(NO3)2(aq) + 2NaI(aq) -> 2NaNO3(aq) + PbI2(s)
What is the net ionic equation for silver chloride with aqueous ammonia solution?
The net ionic equation for silver chloride (AgCl) reacting with aqueous ammonia (NH3) solution is: Ag+ (from AgCl) + 2NH3 -> Ag(NH3)2+ + Cl- where only the species that undergo a change are included. This represents the formation of a complex ion silver ammine ion.

Does heptene decolourize bromine water in the dark?
Yes, heptene will decolorize bromine water in the dark due to its ability to undergo addition reactions with bromine. This reaction forms a colorless compound, resulting in the decolorization of the bromine water.
Will bromine undergo sublimation?
Yes, bromine can undergo sublimation. At room temperature, bromine is a liquid, but if the temperature is increased above its boiling point of 58.8°C, bromine can directly change from a solid to a gas without passing through the liquid phase.
