WebPhenol reacts withBr2inCCl4at low temperature to giveo and pbromophenol However when phenol is treated with excess of aqueous bromine solution 246tribromophenol is … WebSolution: In presence of non-polar solvent (C S 2) the ionization of phenol is suppressed. The ring is slightly activated and hence mono substitution occurs. On the other hand with Br2 water phenol forms 2,4,6 -tribromo phenol. In aqueous solution, phenol ionizes to give phenoxide ion. Due to the presence of negative charge on oxygen, the ...

When phenol is treated with CHCl3 and NaOH , the product formed …
WebReplacing -OH by bromine. Rather than using hydrobromic acid, you usually treat the alcohol with a mixture of sodium or potassium bromide and concentrated sulphuric acid. This produces hydrogen bromide which reacts with the alcohol. The mixture is warmed to distil off the bromoalkane. Note: You will find practical details of this reaction on ... WebMar 14, 2024 · Hence, salicylic acid will react with bromine water, but benzoic acid won't. Physically, bromine water is orange due to $\ce{Br2}$, but if the bromine reacts, then the orange color will no longer be present. Thus, the solution will turn colorless upon contact with salicylic acid, and will stay orange in contact with benzoic acid. WebPhenol forms different products if it reacts with bromine in different solvents e.g. In CS2 2,4,6- tribromophenol is not formed. BUT: in CS2, a mixture of 2-bromophenol and 4 … border poll good friday agreement
