Q. Arrange the following in the order of
(i) increasing bond strength $HCl, HBr, HF, HI$
(ii) increasing oxidation number of iodine
$ I_2,HI,HIO_4,ICl $

IIT JEEIIT JEE 1986The p-Block Elements - Part2

Solution:

(i) Bond strength is inversely related to bond length. Hence,
bond energy : $HI < HBr < HCl < HF$
$(ii) HI(- 1) < I_2(O) < ICl(+1) < HIO_4 (+7)$
