WebJan 23, 2024 · The high proportion of carbon in phenol means that you need a very high proportion of oxygen to phenol to get complete combustion. Look at the equation. As a general rule, the hydrogen in a molecule tends to get what oxygen is available first, leaving the carbon to form carbon itself, or carbon monoxide, if there isn't enough oxygen to go … WebAnswer (1 of 8): Carbon dioxide is a very weak electrophile. So, the reaction with moderate nucleophile phenol is very poor. In order to increase the rate of reaction, NaOH is added to produce stronger phenoxide nucleophile. Here, the phenoxide is ortho, para directing. But we get mostly the ort...

It isn't acidic enough. Note: The formation of carbon dioxide when an acid reacts with a carbonate is a two-stage process. In the first step a carbonate ion picks up a hydrogen ion to give a ...
WebJan 23, 2024 · Example 1: Reaction with Bromine Water. If bromine water is added to a solution of phenol in water, the bromine water is decolorized and a white precipitate is formed which smells of antiseptic. The precipitate is 2,4,6-tribromophenol. Notice the multiple substitution around the ring - into all the activated positions. WebTreatment of sodium salt of phenol with C O2 under pressure brings about substitution of the −COOH group for the hydrogen of the ring. This is called as Kolbe's reaction.
