We’re being asked to determine which bond is expected to be the most polar.
We will determine the difference between the electronegativity (ΔEN) of the atoms in each bond. Recall that the greater the electronegativity difference the more polar the bond.
↑ΔEN = ↑ polar
We will refer to the periodic table to get the electronegativity for each atom.
Calculate for ΔEN of each bond
Which of the following bonds would you expect to be the most polar?
