Question

Which one of the following has the highest dipole moment?

• A. $As H_3$
• B. $SbH_3$
• C. $PH_3$
• D. $NH_3$

Answer 1

Answer: (D)

$NH_3$

Answer 2

In the given molecules nitrogen has greater
electronegativity. So, it has greater dipole moment
and correct order of dipole moment is
$NH_3 > PH_3 > AsH_3 > SbH_3$
