Can phenol react with magnesium?
They will react with metals near the top of the reactivity series i.e. potassium, sodium, lithium, calcium and magnesium. Phenol is much more acidic than water or ethanol and as well as reacting with the reactive metals mentioned it will also react with strong bases i.e. hydroxides.
What happens when sodium hydroxide reacts with phenol?
So, we can say that the reaction between phenol and sodium hydroxide is an acid-base reaction which is also known as neutralisation reaction. We know that, when an acid reacts with a base, the products formed are a salt and a water molecule.
Does phenol react with sodium?
Phenol reacts with sodium hydroxide solution to give a colourless solution containing sodium phenoxide. Phenol isn’t acidic enough to react with either of these. Unlike the majority of acids, phenol doesn’t give carbon dioxide when you mix it with one of these.
Does phenol react with Lucas reagent?
Phenols do not react under the reaction conditions of Lucas test and/or chromic acid test.
Does phenol react with nahco3?
Phenol is an acid but does not react with sodium bicarbonate solution.
What forms when phenol reacts with sodium hydroxide?
When phenol reacts with NaOH (sodium hydroxide), sodium phenoxide is formed.
What forms when phenol reacts with sodium?
Phenoxide ion undergoes electrophilic substitution with carbon dioxide ( a weak electrophile) because phenoxide ion is more reactive than phenol. Salicylic acid is formed as a major product.
Why is phenol soluble in NaOH but not NaHCO3?
Water-insoluble compounds that are soluble in 5% NaOH are then tested with 5% sodium hydrogen carbonate (NaHCO3). Phenols are less acidic than carboxylic acids and do not react with NaHCO3 to form water-soluble salts. As a result, phenols are insoluble in 5% NaCHO3.
What is the major product obtained on the interaction of phenol with sodium hydroxide and carbon dioxide?
hydroxybenzoic acid
If Phenol is treated with sodium hydroxide it generates sodium phenoxide ion. The formed phenoxide ion is more reactive than phenol so it undergoes electrophilic aromatic substitution with carbon dioxide which is a weak electrophile and ortho hydroxybenzoic acid is formed as the major product.
What happens when phenol reacts with?
How does phenol react with?
Reactions of phenols Much of the chemistry of phenols is like that of alcohols. For example, phenols react with acids to give esters, and phenoxide ions (ArO−) can be good nucleophiles in Williamson ether synthesis.
What happens when Phenol reacts with sodium hydroxide?
When phenol reacts with sodium hydroxide it gives sodium phenoxide (sodium salt of phenol). The reaction takes place by removal of H+ ion from phenol by OH- ions of NaOH which is eliminated as water. The Na+ ion then combines with the phenoxide ion to form sodium phenoxide. It will be an acid-base reaction resulting in formation of salt + water:
Is the product of phenol and NaOH soluble in water?
Phenol is not a soluble organic in water and exists as a separate layer. But, when phenol reacts with aqueous NaOH, product sodium phenoate is soluble in water. Though phenol can be identified from alcohols from the reaction with aqueous NaOH, you cannot idenstify phenol from carboxylic acids because, carboxylic acids react with aqueous NaOH.
Why is phenol found in a colourless solution?
You can recognise phenol because: It is fairly insoluble in water. It reacts with sodium hydroxide solution to give a colourless solution (and therefore must be acidic). It doesn’t produce carbon dioxide with sodium carbonate or hydrogencarbonate solutions (and so must be only very weakly acidic).
What happens when phenol is mixed with ethanoic acid?
If you simply use phenol and ethanoic anhydride, phenyl ethanoate is formed together with ethanoic acid. This reaction isn’t important itself, but a very similar reaction is involved in the manufacture of aspirin (covered in detail on another page – link below).
