kolbe reaction explain​

Answer 1

The Kolbe–Schmitt reaction or Kolbe process (named after Hermann Kolbe and Rudolf Schmitt) is a carboxylation chemical reaction that proceeds by heating sodium phenoxide (the sodium salt of phenol) with carbon dioxide under pressure (100 atm, 125 °C), then treating the product with sulfuric acid.

When phenol is treated with sodium hydroxide, sodium phenoxide is produced, which on treating with carbon dioxide, followed by acidification, undergoest electrophilic substitution to give a hydroxybenzene acid as the main product.
