Question

Increasing order of bond dissociation enthalpy of halogens

Answer 1

Answer:

F2 is expected to have highest bond dissociation enthalpy but it is Cl2…. the correct decreasing order isCl2>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 http://atoms….so the bond between two fluorine gets weaker amd need ...
