WebPhenol can be synthesized from, for instance, chlorobenzene. The first step of the reaction is addition of chlorobenzene to a solution of sodium hydroxide (NaOH) in water at 370°C. The sodium hydroxide dissociates, producing hydroxide ions that deprotonate the benzene ring, forming a benzyne intermediate. WebPhenol in presence of sodium hydroxide reacts with chloroform to form salicyladehyde. The reaction is knowns as The reaction is known as Show more NEET Chemistry Iodoform …

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 ... WebPhenol is considered as a weak acid and NaOH is a strong base. Hence, this reaction is considered as an acid-base reaction or also known as a neutralization reaction. We know …
