1. Mark the following statements (A-E) as true or false
A. The halogen bond dissociation energy decreases in the row Cl2 Br2 I2 because of repulsion between the electrons in the lower shells.
B. The melting points of the dihalogens increase down the group because the interactions between the dihalogen molecules get stronger
C. The electronegativity of the halogens decreases down the group because of the decrease of the electron affinity and the increase of the ionization energy.
D. The unusually low bond dissociation energy of the F2 molecule is a direct result of the high electronegativity of fluorine
E. The high reactivity of fluorine is in part due to the low bond dissociation energy of the F2 molecule
