Conformations and Cyclic Allanes (cyclohexane)

Question 1

Define conformations

Answer 1

Different arrangements of atoms that result in the rotating of c-c single bonds

Question 2

What is eclipsed and how does it relate to energy?

Answer 2

Atoms align in Newman projection.
Has high energy due to e- repulsion causing tension

Question 3

What is staggered conformations and how does it relate to energy?

Answer 3

Does not align in Newman projections.
Has less e- repulsion therefore lower in energy.

In alkene structures

Question 4

What is a Newman projection?

Answer 4

A representation of one conformation that looks down a bond to show the spatial arrangement
