Problem: Calculate the effective charges on the Br atom of the HBr molecule in units of the electronic charge, e.

FREE Expert Solution

We have to calculate the effective charge on the Br atom of the HBr molecule in units of the electronic charge, e.


To solve this problem, we need to have the bond length and dipole moment of the HBr molecule.

We can look up these on the internet or in a chemistry textbook.

Bond length = 1.42 Å

Dipole moment = 0.80 D


Dipole moment (μ) is defined as the product of charge separation (bond length) and the magnitude of charges.

μ = q·r

Where,

μ = dipole moment

q = magnitude of charge

r = bond length
