MHT CET 2026 Chemistry question

Which of the following order of dipole moment for stated molecules is correct?

(A)
(B)
(C)
(D)Correct

Answer: (D)

Solution

is trigonal planar and symmetrical, so its three B-F bond dipoles cancel and the net dipole moment is zero. and are both pyramidal with a lone pair on nitrogen. In the N-H bond dipoles (N is more electronegative) point towards N, in the same direction as the lone-pair dipole, so they add up
