Dipole moment of MH 3 decreases down the group as the electronegativity of the central atom M decreases.

Q. Dipole moment of the hydrides of group 15 elements decreases in the order:

$A s H_{3} > B i H_{3} > S b H_{3} > N H_{3} > P H_{3}$

$B i H_{3} > S b H_{3} > A s H_{3} > P H_{3} > N H_{3}$

$N H_{3} > P H_{3} > A s H_{3} > S b H_{3} > B i H_{3}$

$P H_{3} > N H_{3} > A s H_{3} > S b H_{3} > B i H_{3}$

Dipole moment of $M H_{3}$ decreases down the group as the electronegativity of the central atom $M$ decreases.

Q. Dipole moment of the hydrides of group 15 elements decreases in the order:

AsH3​>BiH3​>SbH3​>NH3​>PH3​

BiH3​>SbH3​>AsH3​>PH3​>NH3​

NH3​>PH3​>AsH3​>SbH3​>BiH3​

PH3​>NH3​>AsH3​>SbH3​>BiH3​

Dipole moment of MH3​ decreases down the group as the electronegativity of the central atom M decreases.

$A s H_{3} > B i H_{3} > S b H_{3} > N H_{3} > P H_{3}$

$B i H_{3} > S b H_{3} > A s H_{3} > P H_{3} > N H_{3}$

$N H_{3} > P H_{3} > A s H_{3} > S b H_{3} > B i H_{3}$

$P H_{3} > N H_{3} > A s H_{3} > S b H_{3} > B i H_{3}$

Dipole moment of $M H_{3}$ decreases down the group as the electronegativity of the central atom $M$ decreases.
