SAMPLE PROBLEM 10.7
(continued)
(b) For COCl2, C has the lowest EN and will be the center atom.
There are 24 valence e-, with 3 atoms attached to the center atom.
C does not have an octet; a pair of non-bonding electrons will move in from the O to produce a double bond.
The shape for an atom with three atom attachments and no non-bonding pairs on the central atom is trigonal planar.
The Cl-C-Cl bond angle will be less than 120o due to the electron density of the C=O.
