Q101E
Question
The molecule XF3 has a dipole moment. Is X boron or phosphorus?
Step-by-Step Solution
Verified Answer
The molecular structure of \({\rm{P}}{{\rm{F}}_{\rm{3}}}\)is not symmetrical and hence dipole does not cancels out.
1Step 1: Concept Introduction
It is a measure of the system's overall polarity .The electric dipole moment gives the separation of positive and negative electrical charges inside a system.
2Step 2: Find lone pair and dipole moment
There are no lone pairs in\({\rm{B}}{{\rm{F}}_{\rm{3}}}\),however one lone pair is present in\({\rm{P}}{{\rm{F}}_{\rm{3}}}\).
Therefore, as a result, the molecular structure of \({\rm{P}}{{\rm{F}}_{\rm{3}}}\) is asymmetrical, and the dipole does not cancel out.
