A simple, dependable method for the detection of oxygen a organic compounds is presented. The method consists of vaporising the sample of organic compound and passing of vapors through a bad of glowing charcoal then through barium hydroxide solution. If the compound is oxygenated, the oxygen will be converted into carbondioxide which is precipitated as barium carbonate upon coming in contact with barium hydroxide solution . The test has been tried out on two classes of students. None of whom had any previous experience in organic qualitative analysis. The average score on a series of ten unknowns was eighty pen cent. correct by the one group and on twenty-seven unknowns the other. group scored the eighty-five per cent
