Dipole moment of NaCl is 8.5 D. interatomic distance between `Na^(+) and Cl^(-)` is 2.36 Å. Calculate the percentage of ionic character of NaCl molecule.

Text Solution

Verified by Experts

If NaCl is 100% ionic then,
`mu_(Na^(+)Cl^(-))=exxd=4.8xx10^(-10)esuxx2.36`Å
`=4.8xx10^(-10)esuxx2.36xx10^(-8)cm=11.328`D
`therefore%` Ionic character`=(mu_("observed"))/(mu_("ionic"))xx100=(8.5xx100)/(11.328)=75.035`
