### 4G.5 7th edition

For ths question, how do I tell the number of possible orientations for degeneracy in both molecules? For a molecule like Ch3Cl that was given in class, I know that it is 4^N, but how do I tell the number of possible orientations for a trigonal bypyramidal structure?

The possible orientations just depend on the atoms involved. For example, CH4 is a tetrahedral just like CH3Cl but only has one possible state to be found in and thus its degeneracy is seen as w=1^n. So this logic would follow with a trigonal bipyramidal- if the atoms attached to the central atom are all the same then there is only one possible state.
