After drawing the structures of both and considering dipole moment, doesn't it seems that all K2O should have more ionic character than LiF? My textbook says its LiF.

  • $\begingroup$ Li and F are very small atoms hence they form strong covalent bond. $\endgroup$ – Yashas Feb 25 '16 at 10:38
  • $\begingroup$ So why they have more ionic character? $\endgroup$ – Reeshabh Ranjan Feb 25 '16 at 10:41
  • $\begingroup$ I do not know the answer, looks like I did not frame my comment properly. It appears more like an answer. $\endgroup$ – Yashas Feb 25 '16 at 10:45
  • $\begingroup$ I don't think one can compare the ionic character of compounds where both the anion and cation are different. I have no idea on what basis one would decide which is more ionic. $\endgroup$ – Yashas Feb 25 '16 at 10:45
