You use paper chromatography to separate the following two molecules. The stationary phase is coated with hexane C6H14 and the mobile phase is water. Which molecule will travel furthest up the paper? Explain using intermolecular forces between molecule and water. OH OH Phenol Napthol
3. Consider a solution containing dipolar molecules each having a positively charged head and a negatively charged tail. In the absence of an electric field the molecules point north (n), south (s), east (e), and west (w) with equal probabilities (distribution shown in Fig. 3a). A different probability distribution (shown in Fig. 3b), however, is found when a field is applied to the solution. P P 14 n e น S 7 16 14 16 n e W s Fig. 3a (field absent) Fig. 3b (field present) a) Determine the direction in which the field has its most positive pole (the polarity of the field). b) In the absence of the field, what is the entropy of the system? c) In the presence of the field, what is the entropy of the system? d) Does the application of the field cause the system to become more ordered or disordered?
