Unit 5: VSEPR Theory

VSEPR Theory

predicts molecular shape of molecule, only look at what is connected to the central atom.

Molecular Geometry

Linear, Trigonal Planar, Tetrahedral, Trigonal Pyramidal, and Bent.

Linear

0 pairs of non bonding on central atom, 2,4 single/bonding electrons on central atom. 180 degrees.

Trigonal Planar

0 pairs of non bonding on central atom, 3,4 single/bonding on central atom.

Tetrahedral

0 pairs of nonbonding on central atom, 4 single/bonding on central atom.

Trigonal Pyramidal

1 pair of nonbonding on central atom, 3 single/bonding on central atom.

Bent

2 pairs of non bonding pairs on central atom, 2 single/bonding on central atom.
