What are induced dipoles?

Answer 1

When a dipole happens to be close to a neutral atom or molecule with no dipole moment, the positive end of the dipole pulls the outer electrons from the other molecule or atom close to it. Or the negative end of the dipole can repel the outer electrons of the neutral molecule or atom. Thus a dipole is induced into what was initially a neutral atom or molecule. The induced dipole won't stay that way; i.e., the induction is not permanent but largely depends upon the environment.
