Reaction of phenol with sodium hydroxide

WebWhen phenol is treated with sodium hydroxide, phenoxide ion is generated. The phenoxide ion generated is more reactive than phenol towards electrophilic aromatic substitution reaction. Hence, it undergoes electrophilic substitution reaction with carbon dioxide, which is a weak electrophile. ... Phenol reacts with aqueous NaOH to produce sodium phenoxide and water Phenol is a weak acid and aqueous sodium hydroxide is a strong base. So, this reaction is a weak acid - strong base reaction. Formed product, sodium phenoxide is a moderately strong base. C 6 H 5 OH + NaOH → C 6 H 5 O - Na + + H 2 O See more Reeaction of phenol and aqueous NaOH can be used to identify alcohols from phenol. Alcohols do not react with aqueous NaOH. You … See more No. Both reactions will give same salt (sodium phenoxide). But, with sodium, hydrogen gas is released. With sodium hydroxide, water is given.
