1. Diagram hyperconjugation showing how it stabilizes staggered conformers of ethane.

2. Explain how this stabilizing process occurs, including the steric factors.

Expert Solution

answer : Some points about Ethane

Ethane molecules can rotate internally around one or more of their bonds so that during a full 360^o rotation, they will change between unstable and relatively stable conformations

In ethane one of its CH₃ group roate around C-C bond

the molecule will alternate three times between an unstable eclipsed conformation and the preferred staggered conformation

ethane rotates towards an eclipsed structure, the electrons in C-H bonds on the different C atoms are drawing closer to each other and therefore experience increased repulsion, introducing a rotation barrier that destabilizes the eclipsed structure.

but the main thing that leads to staggered conformation is due to preferential stabilization through hyperconjugation

1. Ethane. Construct two models of ethane and arrange one in a fully staggered conformation and the other in a fully eclipsed conformation. a) Draw both of these conformations using the Newman, “sawhorse” and dash-wedge drawing conventions. b) Locate all the planes of symmetry in the two conformations. c) By how many degrees must one rotate one carbon atom with respect to the other to carry a staggered conformation into an eclipsed conformation (or vice versa). d) By how many...
