Chemistry · Chemical Bonding
Even though fluorine is significantly more electronegative than hydrogen, the net dipole moment of NH3 is greater than that of NF3. This is because ___________.
- 1The total net charge on the NH3 molecule is positive
- 2The lone pair orbital dipole moment in NF3 opposes the resultant dipole moment of the N-F bonds✓
- 3Steric hindrance and repulsion between nitrogen and fluorine weaken the bonds in NF3
- 4There is an extra lone pair of electrons present on the nitrogen atom in NF3
Correct answer
The lone pair orbital dipole moment in NF3 opposes the resultant dipole moment of the N-F bonds
