This is a hexagon.

With carbons it becomes
cyclohexane.

Each carbon has four bonds.

But cyclohexane is not flat.

Viewed from the side it looks like a chair.

mountainvalley
Chairs have mountains and
valleys, like this.
![Page 10: Chairs! the tutorial](https://reader036.fdocuments.net/reader036/viewer/2022082704/558e823b1a28ab8c528b458d/html5/thumbnails/10.jpg)

Or like this.
![Page 11: Chairs! the tutorial](https://reader036.fdocuments.net/reader036/viewer/2022082704/558e823b1a28ab8c528b458d/html5/thumbnails/11.jpg)
Chairs constantly flip between the two
orientations.
![Page 12: Chairs! the tutorial](https://reader036.fdocuments.net/reader036/viewer/2022082704/558e823b1a28ab8c528b458d/html5/thumbnails/12.jpg)
mountain
valley
When chairs flip, mountains become valleys and valleys become mountains.
![Page 13: Chairs! the tutorial](https://reader036.fdocuments.net/reader036/viewer/2022082704/558e823b1a28ab8c528b458d/html5/thumbnails/13.jpg)
The trick is to know which mountain
became which valley and vice versa.

The orientation of the bonds also
changes, but up stays up.

Downs on mountains are parallel to the bonds two steps
away on the chair.

Likewise, ups on valleys are parallel to bonds two steps
away.
