The high oxidising power of fluorine in due to its

Options

  1. Ahigh electron affinity
  2. Bhigh heat of dissociation and low heat of hydration
  3. Clow heat of dissociation and high heat of hydration
  4. Dhigh heat of dissociation and high heat of hydration

Correct answer

C. low heat of dissociation and high heat of hydration

Step-by-step solution

The high oxidising power of fluorine is due to its low heat of dissociation and high heat of hydration. Due to its smallest size, there is considerable repulsion in the non-bonding electrons which weakens the F-F bond. Thus, bond dissociation energy of F₂ is low.
