### 9.75 positional disorder in cis vs trans molecules

Posted:

**Thu Jan 26, 2017 12:21 am**"Considering positional disorder, would you expect a crystal of octahedral cis-MX2Y4 to have the same, higher, or lower residual entropy than the corresponding trans isomer? Explain your conclusion."

The answer key says that for the cis compound there will be 12 different orientations.

Besides for using trial and error and drawing out each configuration, is there some other way to arrive at the answer?
