hydroxy

• class of alcohol depends on

  • no. of alpha hydrogen (H on OH bearing C)
• why heat w immediate distillation for aldehyde


  aldehyde bp lower than alcohol ( pdpd vs pdpd & Hb ) thus aldehyde formed distilled off once formed
• acidity: phenol > water > alcohol

  • Pho- vs OH- : p orb lp e- in O overlaps with pi e-cloud of BR, lp e- delocalised in ring, dispersing negative charge on O, stabilizing ring
• acidity: phenol > water > alcohol

  • Pho- vs OH- : p orb lp e- in O overlaps with pi e-cloud of BR, lp e- delocalised in ring, dispersing negative charge on O, stabilizing ring
  • OH- vs RO- : RO- less stable as e- donating effect of AG will increase e- density and intensify negative charge on O atom, less stable
