Multiple choice

Correct order of increasing dipole moment of HF, HCl, HBr and HI is

  1. HF< HCl < HBr < HI

  2. HI< HCl < HBr < HF

  3. HI< HCl < HF < HBr

  4. HI< HBr < HCl < HF

  5. HCl< HF < HBr < HI

D Correct answer
Explanation

With increase in electronegativity, difference between the bonded atoms, dipole moment increases. On moving down the group, electronegativity decreases. So, the correct order is HI< HBr < HCl < HF.
