1. The problem statement, all variables and given/known data What has more ionic character NaF or NaCl?Covalent? 2. Relevant equations Measured Dipole moment of NaF 27.2e^-30 Measured dipole moment of NaCl 30e^-30 Dipole moment=qd Fractional ionic character=measured dipole moment/qd Equilibrium separation of NaCl =.236nm Equilibrium separation of NaF=.193nm 3. The attempt at a solution What I did is this factional ionic character of NaF is 27.2e^-30/((1.6e^-19)(.193e^-9))= 88% and NaCl is 30e^-30/((1.6e^-19)(.236e^-9))= 79% so what I would take from this is that NaCl is more ionic because of the lower percentage and NaF is more covalent due to a a fractional ionic of 88%. However this is confusing me because I would think based on electro negativity difference NaF would be ionic because higher at 3.05 vs 2.23. Which is right? Also which has more ionic character?
