Answer:
Cl2
Explanation: please mark it brainliest and rate
- F2 is expected to have highest bond dissociation enthalpy but it is Cl2….
- The correct decreasing order is Cl2>Br2>F2>I2 is is so because fluorine atom has very small size due to which there is a high inter electronic repulsion between two fluorine atoms….so the bond between two fluorine gets weaker amd need less energy
- Whereas in chlorine, the last electron enters into 3rd shell contributing less repulsion
