Question

Show that BeF3 molecule has zero dipole moment

Answer 1

BeF3 has a triangular shape.the resultant of any two of dipole vector is opposite to the third one . Therefore the resultant is ZERO

Answer 2

BF3 HAS 0 DIPOLE MOMENT WHILE NH3 HAS A NET DIPOLE MOMENT 1.49DY EXPLAIN. ... Thus, the shape of the molecule (trigonal planar) is such that the bond dipole moments add up to zero. In NH3 molecule, NH3 has a pyramidal structure.Oct 13, 2016
