WebIn general, low polarity compounds have higher R f values than higher polarity compounds. Summary In general, the adsorptivity of compounds increases with increased polarity (i.e. the more polar the compound then the stronger it binds to the adsorbent). The eluting power of solvents increases with polarity. Therefore, low polarity compounds … WebIn addition, for determining the polarity of a bond, you must find the difference of electronegativity of the atoms involved. Also, if the difference is amid 0.4 and 1.7 then the bond will appear polar. But, if the difference is greater than this, then the bond will have an ionic character. Besides, it means that the electron of the bond is ...
