  • To avoid formation of phosgene from chlorofrom we add:
    CH3OH
    CH3COOH
    CH3CHO
    C2H5OH
  • If chloroform is kept in open, in presence of sunlight then
    Poisonous gas phosgene is evolved
    polymerisation take place
    explosion takes place
    no reaction
  • AgNO3 does not give a precipitate with chloroform because :
    CHCl3 is an organic compound
    CHCl3 is insoluble in water
    CHCl3 does not ionises in water
    AgNO3 is insoluble in chloroform
  • Freon-12 is:
    CHClF2
    CHFCl2
    CCl2F2
    CClf3
  • Which is least active to hydrolysis :
    methyl chloride
    vinyl chloride
    butyl chloride
    allyl chloride
