उत्तर १
1) ClO2 is an excellent bleaching agent. It is 30 times stronger bleaching agent then the Cl2. It is used as a bleaching agerit for paper pulp in paper industry and in textile industry
2)ClO2 is also a powerful oxidising agent and chlorinating agent. It acts as a germicide for disinfecting water. It is used for purifying drinking water.

Give reason to explain why ClF3 exists but FCl3 does not exist.
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.
Arrange the following in the increasing order of the property mentioned:
MF, MCl, MBr, MI (ionic character)
