Multiple choice

Which of the following trends of properties is incorrect?

  1. Reducing nature: HF < HCl < HBr < HI

  2. Bond length: HF < HCl < HBr < HI

  3. Acidic strength: HF < HCl < HBr < HI

  4. Dipole moment: HF < HCl < HBr < HI

  5. All of the above are correct.

D Correct answer
Explanation

Dipole moment of hydrogen halides decreases down the group with decrease in electronegativty of halogens. Thus, the correct order of dipole moment is HF > HCl > HBr > HI.
