Electron pair repulsion theory
  • Way to predict the shapes of polyatomic
    molecules.
  • It is stated minimizing the electrostatic
    repulsion between electron pairs in the valence
    shell.

7
From the theory
  • The phenyl ethanoate can be divided into four
    parts
  • The shape of the first carbon atom is tetrahedral
    with sp3 hybridized orbital.

The angle is 109.5
8
  • The second carbon atom is trigonal planar with
    sp2 hybridized orbital.

The angle is 120
9
  • The oxygen between carbon atom and benzene is V
    shape. The hybridization is sp3

The C-O-C angle is 109.5
10
  • Benzene
  • The hybridization of each carbon is sp2
  • Due to the delocalized electrons, the bond
    lengths between carbon-carbon are the same.

The C-C-C angle is 120
