The dipole moment of LiH is 1.964 xx10^(...

The dipole moment of `LiH` is `1.964 xx10^(-29)C-m` and the interatomic distance between `Li` and `H` in this molecule is `1.596Å`. What is the percentage of ionic character in `LiH`?

Text Solution

Verified by Experts

Theoretical dipole moment (dipole moment for 100% ionic character)
`=` (electronic charge) `xx` (inter-atomic distance)
`=(1.602xx10^(-19)C)xx(1.596xx10^(-10)m)`
`=2.557xx10^(-29)cm.`
Percentage ionic character `=("Experimental value of "mu_("observed"))/("Theoretical value of "mu_(ionic))xx100=(1.964xx10^(-29)(Cm))/((2.557xx10^(-29)Cm))xx100=76.8%`
