Problem: The molecule XF3 has a dipole moment. Is X boron or phosphorus?

🤓 Based on our data, we think this question is relevant for Professor Dixon's class at UCF.

FREE Expert Solution

Both Boron (B) and Phosphorus (P) are less electronegative than F.

Since the molecule XF3 has a net dipole moment, we have to find the structure  where the dipole moment towards F do not cancel out.

Recall that some molecular shapes are inherently asymmetrical and always lead to polar compounds, as shown below.
