The percentage of ionic character of LiH is 76.81% and the bond length is 1.596Å. Wha is the value of dipole moment of LiH molecule? [1D=3.335xx10^(-30)C*m]

The percentage of ionic character of LiH is 76.81% and the bond length

1.	The percentage of ionic character of LiH is 76.81% and the bond length is 1.596Å. Wha is the value of dipole moment of LiH molecule? [1D=3.335xx10^(-30)C*m]
Answer» Solution :If the molecule is 100% ionic, then `mu_("ionic")=qxxd=1.602xx10^(-19)Cxx1.596xx10^(-10)m` `=2.557xx10^(-29)Cm` `%` ionic CHARACTER`=(mu_("observed"))/(mu_("ionic"))XX100` `thereforemu_("observed")=("% ionic character"xxmu_("ionic"))/(100)` `=(76.81xx2.557x10^(-29))/(100)=1.96xx10^(-29)Cm` `=(1.96xx10^(-29))/(3.335xx10^(-30))D=5.07D`
