NF3 is pyramidal. There are several variants of bending, where the most common is AX2E2 where two covalent bonds and two lone pairs of the central atom (A) form a complete 8-electron shell. generic formula: AX 2 E. example: ozone O 3. This bent shape falls under the trigonal planar shape, because if you were to remove one bond off the trigonal planar molecule, it would form a bent shape. The lone electron pairs exerts a little extra repulsion on the three bonding hydrogen atoms to create a slight compression to a 107 o bond angle.The molecule is trigonal pyramid molecular geometry because the lone electron pair, although still exerting its influence, is invisible when looking at molecular geometry. 2 lone pairs and 2 bonds.

For a bent tetrahedral geometry, the bond angle is much less than 109° while for a bent trigonal planar geometry, the bond angle is much less than 120°. BENT molecule. trigonal planar bent trigonal pyramidal. Trigonal planar is a molecular shape that results when there are three bonds and no lone pairs around the central atom in the molecule. Certain atoms, such as oxygen, will almost always set their two (or more) covalent bonds in non-collinear directions due to their electron configuration.
