What happens when chlorobenzene is subjected to hydrolysis?
Advertisements
उत्तर
Chlorobenzene does not undergo hydrolysis under normal conditions. However, it undergoes hydrolysis when heated in an aqueous sodium hydroxide solution at 623 K and 300 atm, forming phenol. The presence of an electron-withdrawing group increases the reactivity of haloarenes.
