An HCl molecule has a dipole moment of 3...

An HCl molecule has a dipole moment of `3.4xx 10^(-30) cm`
. Assuming that equal and opposite charges lie on the two
atoms to from a dipole, what is the magnitude of this
charge? The separation between the two atoms of HCl is
`1.0xx10^(-10)m` .

Text Solution

Verified by Experts

If the charges on the two atoms are q,-q,
`q(1.0xx10(-10)m) = 3.4 xx 10(-30)` cm
or, ` q = 3.4 xx 10 (-20) C
. Note that this is less then the charge of a proton. Can
you explain, how such a charge can appear on an atom?
