$NH_3$

Vedclass · Answer

(A) As we move from top to bottom in a group,the dipole moment of hydrides of the elements of that particular group decreases due to an increase in the size of the central atom and a decrease in electronegativity.$NH_3$ has the highest dipole moment because nitrogen is the most electronegative element in the group,leading to a greater polarity of the $N-H$ bond.The order of dipole moment for the given hydrides is:$NH_3 > PH_3 > AsH_3 > SbH_3$

Which of the following has the highest dipole moment?
