Conformations [ENDORSED]

[GabiFujita_1B]

What are all the types of conformations of cyclopropanes?

[Bryce Bentley 1l]

cyclopropane has only one conformation; it is only found with all of its carbon atoms in the same plane. That's why it is a very unstable molecule

[KelseyKobayashi_2M]

Will we need to know/draw the most stable forms of molecules?

[Desiree Martin 2A]

We need to understand which conformation represents which cycloalkane. For example, for cyclopropane, there is only one conformation being cyclopropane where all C's are on the same plane. For cyclobutane, the most stable conformation is the butterfly. For cyclopentane, the most stable conformation is the envelope. Finally, for cyclohexane, the most stable conformation is the chair. This is the only conformation we are expected to know how to draw.

Will we need to know/draw the most stable forms of molecules?

For alkanes, using Newman projections, yes. As I did in class.

Also, as discussed in class, of the cycloalkanes, drawing cyclohexane's conformations is expected. This is why I am spending the most time on cyclohexane.

For the other cycloalkanes know the name of the most stable conformation. Students will not be expected to draw butterfly and envelope conformations.
