Question

Non-polar molecules possess...................

• A. permanent dipole moment
• B. partial charge
• C. no dipole moment
• D. instantaneous dipole moment

Answer 1

Answer:

D. instantaneous dipole moment

• Even in non-polar molecules, the electrons are constantly in motion. At any given instant, the distribution of electrons may be uneven, leading to a temporary, fleeting separation of charge.

• This temporary, uneven electron distribution creates a short-lived, or instantaneous dipole. This phenomenon is also known as a momentary dipole or a temporary dipole.

• The strength and duration of this instantaneous dipole are very small.
