Choose all of the molecules that can have both cis and trans configurations.
I understand the cyclohexane does not fit the requirements, and neither does a molecule with a triple bond. But does the molecule with a ketone? I feel like A-C fit the requirements for having both cis and trans configurations.

A. Enantiomers: Certain substances have the unique property of rotating the plane of plane-polarized light. Such light rotation is detectable with the aid of a polarimeter. In order for a molecule to be optically active it must be chiral. Chiral objects lack a plane of symmetry and are non-superimposable on their mirror images. A sp?- hybridized carbon atom can fulfill these requirements if all four of its substituents are different. 1. Methane a) Prepare a methane molecule and then substitute...
