Pre-lecture Reading Assignment: Cyclic Conformers
Quick Intro
Cyclic alkanes have different types of conformers than acyclic alkanes. We will focus on 6-membered rings (cyclohexanes) and their chair conformations. You will need a phyiscal model kit in class to help understand these three-dimensional structures and translate them into two -dimensional drawings.
Objectives
- Identify the types of strain present in different cycloalkanes.
- Draw both chair conformers for cyclohexane.
- Draw chair conformers for substituted cyclohexane derivatives.
- Perform "chair flips" for cyclohexan derivatives.
- Distinguish between relative energies for different conformers of cyclohexane derivatives and explain the cause of the energy difference.
