Answer:
The Dipole moment is 6.77 Debyes.
Explanation:
Given bond length of HBr molecule = 1.41 A°,
We also know charges on H and Br(+1 and -1 respectively)
Charge on H = (+1) (absolute charge of electron);
Charge on Br = (-1) (absolute charge of electron);
Since absolute charge on electron = ;
Therefore charge on H = Coulomb;
charge on Br =
We know Dipole Moment = Charge Distance;
Here,
Distance = Bond Length = 1.41 A° = 1.41 ;
and charge on atom = Coulomb;
Therefore,
Dipole Moment = Distance Charge
Dipole Moment = ;
Dipole Moment = SI units.
The conversion factor of for SI units to Debye is 2.9989
Therefore,
Dipole Moment = 2.25882
Dipole Moment = 6.77 Debye.
