Question

18. Calculate the percent ionic character of the bond in CO which has a dipole moment( u ) = 0.11 D and distance between partial charges (r) = 113 picometer. (1D = 3.336x10-30 C•m ; le = 1.6022x10-19 C) A) 2.0% B) 0.20% C) 20.% D) 1.8% E) 18%

Answer 1

when electron pair shared between two similar ataus it is shared equally, H- H U -ul etc when electron pair shared between two disimilar atours shared electron pair is attracted muove towards more Electronegative element. Af a result it gets partial the charge and ourer geta partial tue charge, dipole cd-,dt) created, is Dipole mourent defined as product of an any of the diple charge and bord length Dipolemavent (A) = d. Here d= bond length &= charge on any one of dipole, Given, dipole moment (M = 0.UD =O11X3.336x10cm distance between charges (9). "SPM : 113x10 km This . distance is band length (d), de l = 11341012m.
