Polarity in molecules

Hi
When talking about the polarity of molecules, if asked about a polar molecule, should we mention that the polar molecule also contains temporary dipoles? And if asked about a hydrogen bond molecule, should we mention that it also contains permanent dipoles and temporary dipoles?

Hi cjbe,
You can mention that a polar molecule also contains temporary dipoles. Remember that the focus should be on the polarity of the molecule i.e. elements have different electronegativities and therefore a dipole is set up. If there is an uneven distribution of charge then overall the molecule is polar. So a polar molecule needs polar bonds and an uneven distribution of charge.
Hope that helps :slight_smile:
