The observed dipole moment of `HCl` is `1.03D`. If the bond length of HCL is `1.3Å`, then the percent ionic character of `H-Cl` bond is

Text Solution

Verified by Experts

`mu_("cal")=Qxxr=(1.6xx10^(-19)C)xx(127xx10^(-12)m)=2.032xx10^(-29)Cm`
`=(2.032xx10^(-29)Cm)xx(1D)/(3.336xx10^(-30)Cm)=6.09D`
% ionic character = `(mu_("obs."))/(mu_("cal"))xx100=(1.03D)/(6.09D)xx100=16.9%`
