polar

In summary, NBr3 is a polar molecule with a trigonal pyramidal geometry. This is due to the uneven distribution of electrons caused by the more electronegative bromine atoms pulling on the shared electrons. NBr3 can also form hydrogen bonds with other molecules containing highly electronegative atoms.

Related to NBr3: Polar or Nonpolar Molecule?

1. Is NBr3 a polar or nonpolar molecule?

NBr3 is a polar molecule.

2. How do you determine if a molecule is polar or nonpolar?

A molecule is polar if it has a net dipole moment, meaning the distribution of its electrons is uneven. This can be determined by looking at the molecule's geometry and the polarity of its bonds.

3. What is the molecular geometry of NBr3?

NBr3 has a trigonal pyramidal geometry, with the nitrogen atom at the center and three bromine atoms forming a pyramid around it.

4. Which atom in NBr3 is more electronegative?

Bromine is more electronegative than nitrogen in NBr3. This means that the bromine atoms exert a greater pull on the shared electrons, creating a polar molecule.

5. Can NBr3 form hydrogen bonds?

Yes, NBr3 can form hydrogen bonds with other molecules that contain hydrogen atoms bonded to highly electronegative atoms such as oxygen, nitrogen, or fluorine.
