Question

which molecule is most difficult to reduce options are F2,Cl2,Br2,I2

Answer 1

Answer:

The answer should be Cl2

Explanation:

The bond dissociation energy of fluorine is however, lower than chlorine and bromine due to its small size its inter electronic repulsion is very high . That's why the the bond dissociation enthalpy follows the order Cl2 >Br2>F2>I2.

thus , Cl2 has greater bond dissociation energy and hence, It is most difficult to reduce Cl2.
