Question

Use the table information about bond energies to answer the question.

Bond: C-Cl C-F H-Cl H-F
Energy (kJ / mol) 339 485 427 565

Which bond is more stable?

H-F
C-Cl
H-Cl
C-F

Answer 1

To determine which bond is more stable, we need to consider the bond energies provided. Generally, a higher bond energy indicates a stronger, more stable bond.

Here are the bond energies given:

- C-Cl: 339 kJ/mol
- C-F: 485 kJ/mol
- H-Cl: 427 kJ/mol
- H-F: 565 kJ/mol

Among these, the bond with the highest energy is H-F at 565 kJ/mol. Therefore, the H-F bond is more stable compared to the others listed.

The answer is **H-F**.
