Question:
Dipole-dipole forces act between the molecules possessing permanent dipole. Ends of dipoles possess ‘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.
Solution:
(c) Partial charge is a small charge developed by displacement of electrons. It is less than unit electronic charge and is represented as δ+ or δ–
