The percent ionic character of a polar b...

The percent ionic character of a polar bond may be computed from the expression Percent ionic character = `(P_("observed"))/(P_("ionic")) xx 100` where P stands for dipole moment.
Based on the values of percent ionic character computed by the above expression, Pauling obtained t expression, percent ionic character = `18 (chi_x - xhi_H)^(1.4)`
where `Chi_x ` and `chi_H` are electronegativity values of a halogen atom and H, respectively.
The variation of percent ionic character and electronegativity difference for H-X(where X is halogen) is shown in Figure:
