Which of the following options describes Kolbe’s reaction correctly?

Options

  1. AKolbe's reaction involves the electrochemical reduction of carboxylic acids to form aldehydes.
  2. BKolbe's reaction is a process in which alkyl halides are treated with alcoholic sodium hydroxide to produce al
  3. CWhen phenol is treated with sodium hydroxide, sodium phenoxide is produced. This sodium phenoxide when treated
  4. DKolbe's reaction is a reaction in which two alcohols are combined in the presence of an acid catalyst to form

Correct answer

C. When phenol is treated with sodium hydroxide, sodium phenoxide is produced. This sodium phenoxide when treated

Step-by-step solution

Correct Option is : (C) When phenol is treated with sodium hydroxide, sodium phenoxide is produced. This sodium phenoxide when treated with carbon dioxide, followed by acidification, undergoes electrophilic substitution to give ortho-hydroxybenzoic acid as the main product. This reaction is known as Kolbe's reaction.
