Calculate the fractional charge on each atom of HBr. The dipole moment

1.	Calculate the fractional charge on each atom of HBr. The dipole moment of HBr is 0.78D and its bond length is 1.41Å. [electronic charge, e=4.8xx10^(-10) esu, 1D=10^(-10)esu*cm].
Answer» SOLUTION :Dipole moment, `mu=qxxd` or, `Q=(mu)/(d)=(0.78xx10^(18)esu*cm)/(1.41xx10^(-8)cm)=0.55xx10^(-10)esu` Fraction of charge `(delta)=("Charge present (q)")/("Electronic charge (e)")` `=(0.55xx10^(-10)esu)/(4.8xx10^(-10)esu)=0.11` `therefore`The fractional charge on HYDROGEN, `delta_(H^(+))=0.11 ` and the fractional charge on BROMINE, `delta_(Br)=-0.11`
