Although B––F bond in BF3 is polar but the dipole moment of BF3 is zero, why?Please answer me in 2 marks |
|
Answer» Answer: Due to t he TRIGONAL PLANAR geometry of BF₃ the three f atoms are oriented in an bond ANGLE of 120 degrees. The resultant of the DIPOLE moment caused two BF bonds is at 180 degrees with the third one. THUS the three get cancelled.Thus ,the net dipole moment is zero. DRAW the diagram. You will get your full 2 marks. All the best |
