Answer of first question is Butyric acid
Butyric acid expected to have lowest RF value
Because Butyric acid is more polar compound among the given list. So Butyric acid moves slowly on TLC plate (It has strong interactions with silica gel. In the mean wile eluting solvent DCM is also not high polar solvent.
Answer of second question is Decane
Decane is highly is nonpolar among the given list
weak Vander walls interactions with stationary phase silica gel.
It moves very fast on TLC plate
