Homework Question 4.25

Postby 404975170 » Sun Jun 10, 2018 11:54 pm

I’m still struggling with distinguishing if the atom is polar or nonpolar. Judging off of the answers to Question 4.25 is the best way to distinguish if it is polar or nonpolar to see if the Lewis structure looks symmetrical and if so it’s nonpolar and if the Lewis structure isn’t then it polar or is there a different trick that is more helpful?

A nonpolar molecule must have zero must have zero electric dipole moment which is possible if the dipole moments cancel. In a polar bond the dipole moments do not cancel.

if dipole moments cancel out then the overall molecule will have zero dipole moment
