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 textCl_2 > textBr_2 > textF_2 > textI_2. Statement II: The correct trend in the covalent character of the metal halides is [textSnCl_4 > textSnCl_2], [textPbCl_4 > textPbCl_2] and [textUF_4 > textUF_6] (or similar Fajan's rule trend). In the light of the above statements, choose the correct answer from the options given below:
