Polar Covalent Bonds (unequal sharing of e‐)

• Electrons tend to spend more time around the more electronegative atom. The result is a partial negative charge, δ–.

• The other atom is “more positive,” or δ+.• The greater the difference in electronegativity, the more polar the bond

Which bond is more polar in each pair? Indicate partial charges.A) B  Cl or C  Cl B) P ‐ Cl or P  F

Polarity Practice

Which bond is more polar? Indicate which atom has the partial negative charge.A) B  Cl or C  ClB) P ‐ Cl or P  F

Dipole Moment (has a magnitude and direction)

*Polar bonds can cancel out and result in no dipole moment /a nonpolar molecule*

Draw Lewis Structures for carbon dioxide and water.

Are there polar bonds present?

Do the polar bonds cancel out?
