question_answer 65)

    Which of the following statements are correct? (a) Among halogens, radius ratio between iodine and fluorine is maximum. (b) Leaving F ? F bond, all halogens have weaker X ? X bond than X ? X bond in interhalogens. (c) Among interhalogen compounds maximum number of atoms are present in iodine fluoride. (d) Interhalogen compounds are more reactive than halogen compounds.

Answer:

                    (a, c, d) Among halogens, radius ratio between iodine and fluorine is maximum because iodine has maximum radius and fluorine has minimum radius. (b) It can be correctly stated as in general interhalogen compounds are more reactive than halogen. This is because X ? X' bond in interhalogen is weaker than X? X bond in halogens except F?F bond. (c) Among interhalogen compounds maximum number of atoms are present in iodine fluoride because radius ratio of iodine and fluorine has maximum value. (d) Interhalogen compounds are more reactive than halogen due to weaker X ? X bond as compared to X ? X of halogen compounds.
