Phenol plus chcl3 and naoh
WebIn the reaction of phenol with `CHCl_(3)` and aqueous `NaOH` at `70^(@)`, the electrophile attacking the ring is: WebThe -OH group attached to the benzene ring in phenol has the effect of making the ring much more reactive than it would otherwise be. For example, as you will find below, phenol will react with a solution of bromine in water (bromine water) in the cold and in the absence of any catalyst. It also reacts with dilute nitric acid, whereas benzene ...

WebJan 23, 2024 · Phenol is a very weak acid and the position of equilibrium lies well to the left. Phenol can lose a hydrogen ion because the phenoxide ion formed is stabilised to some extent. The negative charge on the oxygen atom is delocalised around the ring. The more stable the ion is, the more likely it is to form. Webphenol is formed . as in presence of NaOH (strong base) the benzene losses it Cl- and bonds with Na leaving OH- to bond with benzyl Sponsored by Oldehealth Science! Not miracles!
