Dipole moments

Postby Matt Sanruk 2H » Sun Nov 03, 2019 1:45 pm

So the dipole moments translate whether or not the molecule is covalent, ionic, or polar?

A molecule will always be covalent because it is covalently bonded. The dipole moment determines whether the covalent bond has ionic or covalent character because of the charge difference. If there is a dipole moment, it is a polar covalent bond, and as a result of the partial positive and partial negative regions, it has ionic character.

How do we determine whether to place a positive or negative dipole moment in the Lewis structure and where to place them?

Ah I see that makes more sense, its just less covalent

The dipole moment also tells us about the charge. The bigger the difference in electronegativity, the larger the charge and vice versa.

a dipole moment occurs when atoms in a molecule share electrons unequally. this means there's a difference in electronegativity, and this creates partially negative and positive regions which gives the molecule ionic character
