Question

Dipole-dipole forces act between the molecules possesing permanent dipoles. The ends of dipoles possess a 'partial charge'. This partial charge is:

• A. more than a unit electronic charge
• B. equal to a unit electronic charge
• C. less than a unit electronic charge
• D. double the unit electronic charge

Answer 1

The correct option is C less than a unit electronic charge

A partial charge is a small charge developed by the displacement of electrons. It is less than a unit electronic charge and is represented as ${\delta }^{+}$ and ${\delta }^{-}$.
They always have values less than $1.6\times {10}^{-19}$ C (one unit charge).
