Meaning of an induced dipole

Postby Zuri Smith 1A » Sat May 19, 2018 10:00 pm

Can someone please explain the meaning of an induced dipole, and what the given energy represents (as it was presented in class -- is this the energy of the attraction? The energy needed to break the bond?)

A dipole is a molecule with a positive charge on one end and a negative charge on the other. One example is H2O, which has a partial positive charge on the hydrogens and a partial negative charge on the oxygen.
An induced dipole is when interactions between two molecules cause one or both of them to have this separation of charges. For example, a HCl molecule has a strong partial positive charge on the hydrogen and a strong partial negative charge on the chlorine, so if it interacts with a non-polar molecule like N2, the charges are strong enough to distort the electrons of N2 so it becomes a dipole.

Ohh ok. So in the cases you mentioned, how is energy involved with dipole interactions? I ask only because of the lecture in class, which discussed different values of energy for different interactions

The energy values he gave refer to the energy of the attraction.
