23. An aqueous mixture of two substances are analysed by both paper chromatography and high performance liquid chromatography (HPLC). In both types of chromatographies, component P of the mixture was bonded more strongly to the stationary phase than component Q. In terms of Rr and Rt, component P has the Retention time, R Retardation factor, Rr lower A lower higher higher lower В lower C higher higher D 24. What is the number of structural isomers that are available for aldehyde with the chemical formula of C4H8O? А 1 В 2 С 3 D 4 25. The following reaction is initiated with UV light: alkane + chlorine → chloroalkane + hydrogen chloride What happens to chlorine in this reaction? A homolytic fission to give an electrophile B homolytic fission to give a free radical C heterolytic fission to give an electrophile D heterolytic fission to give a free radical

The following statements are true for any chromatographic analysis except: The analyte component interacting most strongly with the stationary phase elute faster than those with weaker interactions. On the other hand, those with least interaction with the mobile phase elute the slowest. Interactions between mobile phase-analyte - stationary phase can be both chemical and physical in nature.
