Ozone and polarity

Postby 305154707 » Sun Dec 02, 2018 6:46 pm

Still a little confused about why ozone ( O3 ) is considered polar (according to the solutions manual). I understand that it doesn't have a symmetrical shape, but how could this matter if there is no net dipole coming into play? The bonds in the molecule are nonpolar so how could this create a polar molecule overall? Thanks.

Ozone (O3) is a polar molecule because when you draw the Lewis structure of the molecule you will see that it has a central oxygen with a lone pair of electrons, one oxygen double bonded to the central oxygen, and one oxygen single bonded to the central oxygen. This lone pair of electrons results in ozone's bent shape. Also, the oxygen with the lone pair has a partially positive charge, while the single bonded oxygen has a partial negative charge. And because of the molecule's shape, the dipole moments don't cancel, so the molecule is polar.

Is the partial positive on the central O and the partial negative on the outer O just due to a greater amount of lone pairs on the outer O, or are there more/other reasons?

Yea its because of the lone pairs and I'm pretty sure the formal charge equation proves that.
