Question

for aneline which is most contributing structure of its canonical forms​

Answer 1

Answer:

In 3 (out of 5) resonance structures of aniline, the N atom has a positive charge and one of the C atoms or the ring (ortho or para to amino group) has a negative charge.

Hence, in the resonance hybrid for aniline, N atom has partial positive charge and C atoms or the ring (ortho or para to amino group) have partial negative charge.

Hence, aniline has dipole moment with the N−atom as the positive end.
