QUESTION #69 Bond Dissociation Enthalpy and Fajan's Rules
Given below are two statements: Statement I: The correct order in terms of bond dissociation enthalpy is Cl₂ > Br₂ > F₂ > I₂. Statement II: The correct trend in the covalent character of the metal halides is [SnCl₄ > SnCl₂], [PbCl₄ > PbCl₂] and [UF₄ > UF₆] (or similar Fajan's rule trend). In the light of the above statements, choose the correct answer from the options given below:
