Question

Dipole-dipole forces act between the molecules possesing permanent dipole. Ends of dipoles posses 'partial charges'. The partial charge is

(a) more than unit electronic charge (b) equal to unit electronic charge

(c) less than unit electronic charge (d) double the unit electronic charge

Answer 1

Answer: (c) less than unit electronic charge

Dipole-dipole forces act between the molecules possessing permanent dipole and ends of dipoles posses 'partial charges'. Partial charges present on ends of a dipole are always less than the unit electronic-charge.

e.g.,
