induced dipole

Postby Funmi Baruwa » Tue Dec 08, 2020 5:23 pm

what is the difference between dipole and induced dipole? And what is the significance of induced dipole ?

also when we say an induced dipole moment has an interaction potential energy of -2 kj mol^-1 are we saying this is the energy given off when two dipoles interact or are we saying this is how much energy is needed for an interaction?

A dipole is when a molecule has an atom(s) with a partially negative charge and an atom(s) with a partially positive charge. For example, H2O has a partially negative oxygen atom and two partially positive hydrogen atoms. An induced dipole is a dipole that is temporarily created when another molecule is nearby.

Induced dipole occurs in molecules that aren't dipoles (as in they don't have polar bonds) having a temporary dipole moment due to changing electron clouds. It's only a temporary uneven distribution of electron density.
For dipoles, there's a permanent uneven distribution of electron density due to one of the atoms having a much higher electronegativity than the other atom.

A dipole refers to a molecule with opposite charges on both ends. Dipoles tend to be for polar molecules.

Induced dipoles are temporary. When an ion or molecule with a dipole comes near a molecule without a true dipole, it will induce the distortion of that molecule's electron cloud, making it have a temporary dipole. These weak and temporary induced dipoles caused by changing electron clouds are typically common for nonpolar molecules.
