Which bond is the more polar bond in each of the following pairs? Select the single best answer.Part 1 of 3⚊PF⚊PCl

To determine which bond is more polar, we need to look at the electronegativity values of the atoms involved. Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons. The atom with the higher electronegativity will pull the electrons closer to itself, creating a partial negative charge, while the other atom will have a partial positive charge. This creates a polar bond.

The electronegativity values for the atoms involved are as follows:

• Phosphorus (P): 2.19
• Fluorine (F): 3.98
• Chlorine (Cl): 3.16

The difference in electronegativity between P and F is 3.98 - 2.19 = 1.79. The difference in electronegativity between P and Cl is 3.16 - 2.19 = 0.97.

The bond with the greater difference in electronegativity will be the more polar bond. Therefore, the PF bond is more polar than the PCl bond.
