Which one of the following arrangements of molecules is correct on the basis of their dipole moments

View answer and explanation

Correct option: D

N{H_3} > N{F_3} > B{F_3}

Option D (

N{H_3} > N{F_3} > B{F_3}

) is correct because the dipole moment of

NH_3

is higher than

NF_3

due to the direction of bond dipoles and lone pair dipole, and

BF_3

has zero dipole moment due to its symmetrical trigonal planar structure.
