For the TLCs shown below, both plates have the exact same materials spotted on each lane (that is, lane 1 of Plate A and lane 1 of Plate B are identical). What is likely difierence betwoen Plate A and B? Aless polar moble phase has been used for Piote A The spots on Plate B were spotted too close togother The top of the developing chamber was laft off for Plate A A less polar mobile phase has beon used for Plate B. Which of the following illustrate an improper way of spotting a TLC plate. Mark all that apply. Arrange the following compounds from highest Rf to lowest Rfon a TLC plate after elution with 50% ethyl acetate/50\%s heptanes. The stationary phase on a standard TLC plate is non-polar volatile basic polar What is the approximate Rf value of the spot on the following TLC plate
