WebWhich type of reaction takes place when phenol is treated with bromine solution? Basically, it is an electrophilic substitution reaction in which the replacement of hydrogen atom present on the ring of phenol takes place by bromine. As the substitution is initiated by using an electrophile, the reaction is named as electrophilic substitution. WebMay 16, 2024 · p- Bromonitrobenzene is certainly more reactive towards Nucleophilic Substitution than m-Bromonitrobenzene. The reasons are as follows, Firstly, due to $-R$ effect of $\ce{NO2}$ group, the positive charge is created on the carbon attached to bromine in para position, which helps to increase thre electrophilicity of that carbon and … el-group-buttonWebActivating substituents or activating groups stabilize the cationic intermediate formed during the substitution by donating electrons into the ring system, by either inductive … el grullo wheels and customs

WebWhen a reactive metal such as sodium is added to phenol, the metal fizzes producing hydrogen gas. The salt [math] is produced. [math] Reaction with Bromine Unlike benzene, phenol is able to undergo electrophilic substitution with halogens at room temperature, without the need for a halogen carrier. WebNitration. Phenols can undergo electrophilic substitution reactions when reacted with dilute nitric acid (HNO 3) at room temperature to give a mixture of 2-nitrophenol and 4-nitrophenol. When concentrated HNO3 is used, the product will be 2,4,6-trinitrophenol instead. A hydrogen atom in the benzene ring is substituted by a nitro (-NO 2) group.

WebMay 20, 2024 · In phenol, the benzene ring is activated towards electrophilic substitution. Therefore, phenol on bromination gives 2,4,6-tribromophenol. If now, 2, 4, 6-tribromophenol is forced to undergo bromination, the group attached to the benzene nucleus makes phenol not suitable to undergo Friedel–Crafts reaction due to adduct formation with Lewis ...
