Question

The bond energy between carbon and oxygen is 358 for a single bond (C–NegativeO) and 745 for a double bond (C=O). Why is the bond energy higher for double-bonded carbon and oxygen (C=O)?(1 point)
Responses

Additional electrons repel each other, increasing the distance between atoms, and increasing bond energy.

Additional bonds require less energy to break, so the bond energy is higher.

Answer 1

Additional bonds require more energy to break, so the bond energy is higher.

Explanation: a C=O has a sigma plus a pi bond (more electron density between the atoms), making the bond shorter and stronger than a single sigma C–O bond, so it takes more energy to break.
