Polar vs. Nonpolar 10/24 Notes
Nonpolar
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?
