Why is NF3 polar?
Understand the Problem
The question is asking why nitrogen trifluoride (NF3) is considered a polar molecule. It likely involves discussing the molecular geometry, electronegativity differences between nitrogen and fluorine, and the overall dipole moment of the molecule.
Answer
NF3 is polar due to its trigonal pyramidal shape and significant electronegativity difference.
NF3 is polar due to the lone pair on the nitrogen atom causing a trigonal pyramidal shape and the significant electronegativity difference between nitrogen and fluorine, resulting in a net dipole moment.
Answer for screen readers
NF3 is polar due to the lone pair on the nitrogen atom causing a trigonal pyramidal shape and the significant electronegativity difference between nitrogen and fluorine, resulting in a net dipole moment.
More Information
NF3 has a trigonal pyramidal shape primarily due to the lone pair on nitrogen. This shape, combined with fluorine's high electronegativity, creates a net dipole moment.
Tips
Students often forget to account for the lone pairs and their impact on the molecular shape and polarity. Ensure to always consider lone pairs when using VSEPR theory.
