The dipole moment of KCl is `3.336xx10^(-29)` coulomb metre which indicates that is a highly polarized molecule. The interatomic distance between `k^(+) and Cl^(-)` in this molecule is ` 2.6XX10^(10)`m . Calculate the dipole moment of KCl molecule, if there were opposite charges of one fundamental unit located at each nucleus the parcentage ionic character of KCl. |

Answer» If there were opposite charges of one fundamental unit , i.e., `q = 1 . 602 xx10^(-19)` coulombs, then `mu = q xxd =(1.602 xx1-^(-19)` coulombs )`xx(2.6 xx10^(-10)m)` `= 4.1652 xx10^(-29)` coulomb metre `mu_("observed")= 3.336xx10^(-29)` coulomb metre `therefore %` ionic character = `(3.336xx10^(-29))/(4.1652 xx10^(-29))xx100 = 80.09%` |
