Select wether the following statements are True or False: Two compounds that are separated on a 10 cm column have a resolution equal to 1.5. If all conditions remain identical, if the length of the column is doubled, the resolution will increase. An example of a stationary phase support used in strong anion exchange would be a quarternary ammonium-functionalized polymer. In normal phase chromatography, a more polar compound will have a higher partition coefficient than a compound that is less polar. In gas chromatography, compound with higher boiling points generally (but not necessarily) elute later than compounds with lower boiling points. In a chromatographic separation, a compound with a capacity factor equal to 1 must spend an equal amount of time in the mobile phase as it does in the stationary phase.
