A hypothetical molecule, X–Y, has a dipole moment of 1.96 D and a bond length of 117 pm. Calculate the percent ionic character of this molecule.

Expert Solution

dipole moment = e*l

e is charge on electron = 1.6*10^-19 C

bond length l = 117pm = 117*10^-12 m

dipole moment = 1.6*10^-19 *117*10^-12 =187.2*10^-31C-m

theoritical value = 1.96D = 1.96*3.335*10^-30 c-m =6.53*10^-30C-m

percentage of ionic charecter = theoriticl value*100/calculated value

= 6.53*10^-30*100/187.2*10-31 = 34% >>> answer
