Phenol with hcl
Phenol is a good nucleophile, meaning it likes to donate electrons, and therefore can form a chemical bond in reactions. Phenol can react with acetyl chloride and acetic anhydride to form esters. Esters are when one or more OH (hydroxyl) groups are replaced by an O-alkyl (alkoxy) group. Zobraziť viac When phenol is reacted with the mixture of $HCN$and $HCl$ it forms aldimine as the intermediate. The catalyst we use for this reaction is $ZnC{l_2}$. Zobraziť viac You might expect phenol to be similar. However, unlike alcohols, phenol reacts so slowly with carboxylic acids that you normally react it with acyl chlorides … Zobraziť viac In aqueous NaOH, there are mobile Na+ and OH-, so alcohol is not able to react with Na+ to form water and salt , as it can be considered as an acid. Thus the … Zobraziť viac Alkylation of phenols by alcohols gave a mixture of 0- and C-alkylated products under the same reaction conditions. 0-alkylation and C-alkylation are parallel … Zobraziť viac Web2. apr 2024 · Complete answer: Phenol is an aromatic compound which contains hydroxyl groups. The mixture of H C N and H C l is reacted with phenol in the presence of a catalyst known as zinc chloride. Further an intermediate product is formed which on hydrolysis yields us p − hydroxybenzaldehyde. The whole reaction will take place in the following steps: 1.
