I am not entirely sure we covered this topic yet, but Professor mentioned that polarity vs. non polarity will become important in our class. Can someone please explain why some molecules, like H2O, which seem like they would be non polar, are actually polar? Could a few more important examples of this also be provided? Thank you!
Molecules are polar when electrons are not equally shared and that means that there is a big difference in electronegativity between the two molecules, making one molecule more negative and the other more positive. Below, I have attached a picture showing H2O being polar.
