Pblock Elementsii Result Question 48
48. Arrange the following in the order of
(i) increasing bond strength
$\mathrm{HCl}, \mathrm{HBr}, \mathrm{HF}, \mathrm{HI}$
(ii) increasing oxidation number of iodine
$\mathrm{I} _2, \mathrm{HI}, \mathrm{HIO} _4, \mathrm{ICl}$
(1986,2 M)
Show Answer
Solution:
- (i) Bond strength is inversely related to bond length. Hence, bond energy : $\mathrm{HI} < \mathrm{HBr} < \mathrm{HCl} < \mathrm{HF}$
(ii) $\mathrm{HI}(-1) < \mathrm{I} _2(0) < \mathrm{ICl}(+1) < \mathrm{HIO} _4(+7)$
