MCQ
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.
  • ✓
    Less than unit electronic charge.
  • D
    Less than unit electronic charge.
✓

Answer

Correct option: C.
Less than unit electronic charge.
Partial charge is a small charge developed by displacement of electrons. It is less than unit electronic charge and is represented as $\delta^+$ or $\ \delta^-.$
