alleryStart learning →Bond energy is the amount of energy needed to do what?
ABend the bond formed
BCool the bond formed
CBreak the bond formed
DCount the bonds formed
Answer & Solution
Correct answer: C. Break the bond formed
1. Two bonded atoms sit at an energy minimum, so pulling them apart costs energy.
2. Bond energy is the amount of energy that must be added to break the bond that has formed.
3. A larger bond energy therefore means a stronger bond.
4. Bond length, which is a different property, is the distance between the two bonded nuclei.
