Account for the following: Fluorine does not exhibit positive oxidation state.
Compare the oxidizing action of F2 and Cl2 by considering parameters such as bond dissociation enthalpy, electron gain enthalpy and hydration enthalpy.
Account for the following :
Acidic character increases from HF to HI.
Give two examples to show the anomalous behaviour of fluorine.
Why are halogens coloured?
Arrange the following in the order of property indicated for the given set:
HF, HCl, HBr, HI - increasing acid strength.
Arrange the following in the decreasing order of their reducing character :
HF, HCl, HBr, HI
Which is the strongest acid in the following:
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.
