The bond length of HCl molecule is 1.275 Å and its dipole moment is 1.03 D . The ionic character of the molecule (in percent) (charge of the electron =4.8 10⁻¹⁰ esu ) is

Step-by-step solution

Given, observed dipole moment =1.03 D Bond length of HCl molecule, d=1.275 Å =1.275 10⁻⁸ ~cm Charge of electron, e⁻=4.8 10⁻¹⁰ esu Percentage ionic character = ? Theoretical value of dipole moment =e d aligned & =4.8 10⁻¹⁰ 1.275 10⁻⁸ esu - cm & =6.12 10⁻¹⁸ esu - cm & =6.12 D aligned Percentage ionic character aligned & = observed dipole moment theoretical value of dipole moment 100 & = 1.03 6.12 100 & =16.83 % aligned
