The dipole moment of LiH is 1.964 xx 10^...

The dipole moment of `LiH` is `1.964 xx 10^(-29)Cm` and interatomic distance between `Li` and `H` in this molecule is `1.6A` What is the per cent ionic character in LiH ? .

Text Solution

Verified by Experts

The dipole moment of `100%` ionic LiH:
=(1electronic charge)(interatomic distance)
`=(1.602 xx 10^(-19)C) (1.6 xx 10^(-10)m)`
` =2.56 xx 10^(-29)cm`
Fractional ionic character
`("Exp. value of dipole moment")/("Theoretical value of dipole moment")`
The bond in `LiH` is `76.8%` ionic.
