MCQ

Identify the INCORRECT statement.

Options

  • The acid strength of the halogen oxoacids increases with the increasing oxidation state of halogen.

  • All hydrides except H2O possess reducing property which increases in the order H2S < H2Se < H2Te.

  • Oxygen has two allotropes O2 and O3 (ozone).

  • Thermal stability of hydrogen halides increases in the order HF < HCI < HBr < HI.
