Dipole moment

Postby Ami_Pant_4G » Sun Nov 03, 2019 5:03 pm

Just for clarification, every covalent bond between two different atoms has a dipole moment, but not every covalently bonded molecule is necessarily polar, right?

If the covalent bond is between two different element then yes it is polar because having a dipole moment means the electrons are not equally shared and there is a difference between any two different element, large or small.

Dipole moments occur when there is a separation of charge, and they arise from differences in electronegativity. The larger the difference in electronegativity, the larger the dipole moment.

yes. Non-polar molecules experience forces called Van Der Walls forces, which create a small dipole moment for a tiny amount of time when there is a difference in charge between two molecules. More polar molecules experience stronger dipole moments because of their innate polarity, meaning these forces are more prolonged and stronger.
