Question

Dipole-dipole forces act between the molecules possessing permanent dipole. Ends of dipoles possess ‘partial charges’. The partial charge is

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

Answer 1

The correct option is B

less than unit electronic charge

• Dipole-dipole forces act between the molecules possessing permanent dipoles.
• Ends of a dipole possess partial charges.
• Charges are shown by Greek letter delta $\left(\delta \right)$.
• Partial charges are always less than the unit electronic charge $(1.6\times {10}^{-19}C)$.

Hence answer is Option (C).
