The non-metal that does not exhibit positive oxidation state is :
1 Fluorine
2 Oxygen
3 Chlorine
4 Iodine
Explanation:
Fluorine is the most electronegative element in periodic table hence it shows -1 oxidation state in all its compounds.

Correct order of bond dissociation energy is
1 \(\mathrm{Br}_{2}>\mathrm{Cl}_{2}\)
2 \(\mathrm{F}_{2}>\mathrm{Cl}_{2}\)
3 \(\mathrm{I}_{2}>\mathrm{F}_{2}\)
4 \(\mathrm{F}_{2}>\mathrm{I}_{2}\)
Explanation:
In general, bond enthalpy or bond dissociation energy of halogen molecules \(\left(\mathrm{X}_{2}\right)\) decreases down the group from \(\mathrm{Cl}_{2}\) to \(\mathrm{I}_{2}\). \(\mathrm{Cl}_{2}>\mathrm{Br}_{2}>\mathrm{F}_{2}>\mathrm{I}_{2}\) \(\mathrm{F}_{2}\) is an exception due to lone pair-lone pair electronic repulsions.
