+ MAD Skillz: Determine which bond is the most polar

1) Determine the electronegativity of each atom. 2) Subtract the bigger number from the smaller

number to get overall polarity.3) The bond with the largest overall polarity is the

most polar

Determine which bond is the most polar.

N-O, C-O, or B-O
