Question

explian why dipole moment of hydrohen halides 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

Hey mate here is the ans of this qun ...

Dipole moment of hydrogen halides decreases from HF to HI because the ionic character in a covalent bond depends on the difference between the electronegativity of the two atoms , therefore the diapole moment decreases....
