  • Which of the following statements are correct? (i) Among halogens, radius ratio between iodine and fluorine is maximum. (ii) Leaving F-F bond, all halogens have weaker X-X bond than X-X' bond in interhalogens.

Which of the following statements are correct?

(i) Among halogens, radius ratio between iodine and fluorine is maximum.

(ii) Leaving F-F bond, all halogens have weaker X-X bond than X-X' bond in interhalogens.

(iii) Among interhalogen compounds, the maximum number of atoms are present in iodine fluoride.

(iv) Interhalogen compounds are more reactive than halogen compounds.

Answers (1)

The answer is the option (i, iii, iv)

Iodine is the largest halogen, while fluorine is the smallest. \frac{R_{Iodine}}{R_{fluorine}} is thus the maximum. A-B bond in interhalogen compound is weaker than A-A bond in halogen compounds; this also means that interhalogen compounds are more reactive.
