polarity question

Postby 604596531 2k » Fri Oct 30, 2015 3:24 pm

When the lewis dot diagram has a set of lone pair and the bonds are all with the same atom is the molecule polar or non polar?

If there is only one lone pair, the molecule should be polar. The lone pair creates asymmetry within the molecule's shape because it is more localized than bonding electrons, creating an uneven distribution of electrons and subsequently changing the overall molecular dipole moment.
