### 4G.5

4G.5 is asking about positional disorder. It gives a random octahedral in the sis structure and trans structure. It says the Cis compound has 12 different orientation while the trans compound only has three. Why are there so many more orientations for the cis one?

The Cis has more because each atom can be present in each plane while the trans structure only allows a certain atom in each plane which restricts the possible states.

### Re: 4G.5

Can someone clarify the differences between cis and trans isomers?

Cis isomers have similar groups placed on the same side of a double bond. Trans isomers have similar groups placed on opposite sides of a double bond.
