Bond Shape

Postby 904914037 » Sat Nov 09, 2019 8:05 pm

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.

Since oxygen has the second highest electronegativity, it attracts electrons more strongly than hydrogen, thus causing an unequal sharing of electrons between the two atoms

The unequal sharing of electrons will result in one atom to have a partial negative and the other atom to have a partial positive and this would cause the molecule to be polar.
