JEE Main Chemistry question

Which of the following properties does not correspond to the order HI<HBr<HCl<HF?

(A)Thermal stability
(B)Reducing powerCorrect
(C)Ionic character
(D)Dipole moment

Answer: (B)

Solution

Thermal stability, ionic character and dipole moment of the hydrogen halides all genuinely increase in the order HI<HBr<HCl<HF (as the bond becomes shorter, more polar and stronger towards ). Reducing power, however,
