Question

Which statement about an instantaneous dipole is not correct?

A) An instantaneous dipole is a temporary dipole formed by the movement of electrons within a molecule. B) London forces are a kind of van der Waals interaction. C) A positive partial charge within a molecule can result when there is a temporary excess of electrons on the opposite end of the molecule. D) When a molecule has an excess of electrons on one side, the neighboring molecules do not necessarily shift their electrons accordingly.

Explanation / Answer

The answer is D : Since when a molecule has unequal distribution of electrons then neighbouring molecule shift its electrons to the molecule having unequal distribution.

When any molecule is having excess electrons to one end then there is formation of positive charge to another end. So neighbouring molecule shifts electron to that positive charge.

so Answer is D :
