MCQ
Which of the following has the highest dipole moment
  • $N{H_3}$
  • B
    $P{H_3}$
  • C
    $Sb{H_3}$
  • D
    $As{H_3}$

Answer

Correct option: A.
$N{H_3}$
a
As we from top to bottom in a group the dipole moment of hydrides of the elements of that particular group decreases dye to increase in the size of the element

So the order of dipole moment of the given hydrides

$NH _3\,>\, PH _3\,>\, AsH _3\,>\, SbH _3$
