solution
%ionic character = observed DMCalculated DM×100we know,Dipole moment = e×dwhere ,e= 1.602×10-19d = distance between the charges i.e.1.59A0 (given in ques) or 1.59×10-10mhence, μ = e×d μ =1.602×10-19×1.59×10-10 μ = 2.547×10-29cm
putting the value ,
we get
%ionic character = 1.964×10-292.547×10-29×100 = 77%
thus covalent character will be (100-77)=23%
