Tetrahedral Electronic Geometry: AB3U Species (One Lone Pair of
Electrons on A)
Some examples of molecules with this geometry are: NH3, NF3, PH3, PCl3, AsH3
These molecules are our first examples of central atoms with lone pairs of electrons.Thus, the electronic and molecular geometries are
different.All three substituents are the same but molecule is polarpolar.
NH3 and NF3 are trigonal pyramidal, polar molecules.

Tetrahedral Electronic Geometry: AB2U2 Species (Two Lone Pairs of Electrons
on A)
Some examples of molecules with this geometry are: H2O, OF2, OCl2, H2S
These molecules are our first examples of central atoms with two lone pairs of electrons.Thus, the electronic and molecular geometries are
different.Both substituents are the same but molecule is polarpolar.
Molecules are angular, bent, or V-shaped and polar.

Tetrahedral Electronic Geometry: ABU3 Species (Three Lone Pairs of
Electrons on A)
Some examples of molecules with this geometry are: HF, HCl, HBr, HI, FCl, IBr
These molecules are examples of central atoms with three lone pairs of electrons.Again, the electronic and molecular geometries are
different. Molecules are linear and polar when the two atoms
are different.Cl2, Br2, I2 are nonpolarnonpolar.

Trigonal Bipyramidal Electronic Geometry: AB5, AB4U, AB3U2, and
AB2U3
Some examples of molecules with this geometry are: PF5, AsF5, PCl5, etc.
These molecules are examples of central atoms with five bonding pairs of electrons.The electronic and molecular geometries are the same.
Molecules are trigonal bipyramidal and nonpolar when all five substituents are the same.If the five substituents are not the same, polar polar
molecules can result, AsF4Cl is an example.
