Question

explian why dipole movement of hydrogen halide decrease from HF to HI ?​

Answer 1

$\huge\bf{\red{\mid{\overline{\underline{your\:answer}}}\mid}}$

★ This is because electronegativity of halogen atom decrease from F to I. hence, the polar character decrease and so is the dipole movement.

Answer 2

The dipole moment of hydrogen halides decreases from HF to HI.Explain this trend. The Ionic character in a covalent bond depends on upon the difference between the electronegativity of the two atoms. ... Therefore, the dipole moment decreases.
