Draw the Lewis structure for NF3. What are its electron-pair and molecular geometries? What is the hybridization of the nitrogen atom? What orbitals on N and F overlap to form bonds between these elements?

Interpretation Introduction

Interpretation:

The Lewis structure for Nitrogen trifluoride (NF3) has to be drawn. The orbitals on N and F overlap to form bonds involving these elements in NF3 and its electron-pair and molecular geometries should be determined.

Concept Introduction:

  • Lewis structures are diagrams that represent the chemical bonding of covalently bonded molecules and coordination compounds.
  • It is also known as Lewis dot structures which represent the bonding between atoms of a molecule and the lone pairs of electrons that may exist in the molecule.
  • The Lewis structure is based on the concept of the octet rule so that the electrons shared in each atom should have 8 electrons in its outer shell.
  • Hybridization is the mixing of valence atomic orbitals to get equivalent hybridized orbitals that having similar characteristics and energy.
  • Geometry of a molecule can be predicted by knowing its hybridization.
  • sp3  hybrid orbitals is produced by hybridization of single s-orbital and three p-orbital.
  • sp2  hybrid orbitals is produced by hybridization between one s-orbital and two p-orbitals.
  • sp  hybrid orbitals is produced by hybridization of single s-orbital and single p-orbital.

Electron geometry is the shape of a molecule predicted by considering both bond electron pairs and lone pair of electrons.

Molecular geometry is the shape of a molecule predicted by considering only bond pair of electrons.

Explanation

The Lewis structure of NF3 is drawn below,

In NF3 molecule there are three fluorine atoms bonded to the central nitrogen atom and nitrogen atom has a lone pair of electrons.  Therefore according to the above mentioned concepts the electron pair and molecular geometry of NF3 are both trigonal pyramidal
