Question

Which of the following is not a correct statement?

Options

• Halogens are strong oxidising agents.

• Halogens are more reactive than interhalogens.

• All halogens are coloured.

• Halogens have maximum negative electron gain enthalpy.

Answer 1

Halogens are more reactive than interhalogens.

Explanation:

Interhalogens are often more reactive than halogens because the binding between two distinct halogens in an interhalogen is weaker than the bond between two identical halogens. This renders interhalogens more unstable and reactive. The other comments about halogens' characteristics are correct.
