To differentiate smokers from nonsmokers an assay for the determination of 2,5-dimethylfuran concentration in whole blood is performed. Explain the concentration of 2, 5-dimethylfuran in blood is directly proportional to the number of cigarettes smoked per day. Individuals who have a 2, 5-dimethylfuran concentration above 0.024 parts per billion (ppb), or 24 parts per trillion (ppt), are likely to identify themselves as smokers. Depict the compound 2,5-dimethylfuran.
