Question

If bcl bond has dipole moment ,why does bcl3 has zeri dipole moments

Answer 1

Explanation:

Hey mate

Bcz B would acquire partial positive charge n Cl would hv partial negative charge due to their diff in electronegativity...

These 3 Cl would compensate the charge on B..

Hence their resultant would be 0

Answer 2

Answer:

Explanation:

B-Cl has a dipole due to the difference in the elctronegativity of boron and chlorine atom. The overall dipole of a molecule also depends on the geometry. The geometry of BCl3 is planar with a bond angle of 120 degree. The resultant dipole of two B-Cl bonds cancels the third one, resulting in net zero dipole.
