प्रश्न
Arrange the following in the decreasing order of their reducing character :
HF, HCl, HBr, HI
Advertisements
उत्तर
The bond length of the given molecules increases down the group. Therefore, the tendency to lose H+ increases down the group. Hence, the decreasing order of reducing character is HI>HBr>HCl>HF.

The reaction \[\ce{3ClO- (aq) -> ClO3- (aq) + 2Cl- (aq) + 2Cl- (aq)}\] is an example of
Statement I: Acid strength increases in the order given as HF << HCl << HBr << HI.
Statement II: As the size of the elements F, Cl, Br, and I increase down the group, the bond strength of HF, HCl, HBr and HI decreases and so the acid strength increases.
In the light of the above statements, choose the correct answer from the options given below.
