Shapes of Simple Molecules
1. The following triatomic compounds must of course be planar. However, their shape may be linear or bent. Choose one of these shapes for each compound.
| Compound | Linear | Bent | Compound | Linear | Bent | |
| HCN | CO2 | |||||
| O3 | H2S | |||||
| SO2 | N2O |
2. The shape assumed by the atoms of
the following compounds may be trigonal-planar,
square-planar, pyramidal or tetrahedral. Choose one of
these shapes for each compound.
Note that these terms generally refer to the configuration of
substituent atoms about a central higher-valenced atom.
| Compound | Trigonal-Planar | Square-Planar | Pyramidal | Tetrahedral |

| CH2Br2 | ||||
| Cl2C=O | ||||
