Phenol

1. About

   • OH group attached to benzene ring
     • OH forms hydrogen bonding with water= slightly soluble
   • Solid @RTP
   • Forms acidic solutions in water

2. Reactions to form Ionic salts

   • NaOH
     • C6H5OH + NaOH➡C6H5O-NA+ + H2O
       • Solid dissolves
       • Forms Sodium Phenoxide
       • Neutralised
   • Na
     • C6H5OH +Na > C6H5O-Na+ +1/2H2
       • effervescence

3. Uses

   • synthesis of dyes
   • manufacture of pharmaceuticals
     • e.g aspirin
   • +aldehydes> resins

4. Halogenation

   • electrophillic substitution
   • C6H5OH+3Br2> 3BrOHC6H2
     • 2,4,6-tribromophenol
