How can I draw 1,2,3,4,5,6-hexachlorocyclohexane with all the chloro groups in axial positions?

There are two kinds of substituents that can be attached to a chair conformation for a cyclohexane - axial substituents and equatorial substituents.

The axial substituents are drawn pointing straight up and straight down on the chair conformation, while the equatorial substituents are drawn pointing out to the sides of the chair.

For cyclohexane, or #C_6H_12#, the axial and equatorial substituents will look like this

As you can see, the axial hydrogens alternate between UP and DOWN positions on the chair.

UP is a term used to describe groups that are coming out of the plane of the page (are placed on a wedge), while DOWN is used to describe groups that are going into the plane of the page (are placed on a dash).

For hexachlorocyclohexane, or #C_6H_6Cl_6#, you must substitute all the axial hydrogens with chloro groups. The chair conformation for such a configuration will look like this (equatorial hydrogens are not drawn)

If you start at the carbon labeled (1) and go clockwise through all the axial chloro groups, youl have UP, DOWN, UP, DOWN, UP, and finally DOWN (the chlorine atom attached to the carbon labeled (6)).

In the same order, the chlorine atoms will be placed on a wedge (carbon 1), on a dash, on a wedge, on a dash, on a wedge, and finally on a dash (carbon 6). The wedge-dash notation for 1,2,3,4,5,6-hexachlorocyclohexane with all the chloro substituents in axial positions looks like this

undefined To draw 1,2,3,4,5,6-hexachlorocyclohexane with all the chloro groups in axial positions, you would arrange the chloro groups alternating up and down around the cyclohexane ring. Each carbon atom in the cyclohexane ring will have one chloro group in the axial position and one in the equatorial position, resulting in a three-dimensional representation of the molecule.

undefined To draw 1,2,3,4,5,6-hexachlorocyclohexane with all the chloro groups in axial positions, you would arrange the six chlorine atoms around the cyclohexane ring in a way that all of them are pointing upward or downward. This arrangement would result in a chair conformation of the cyclohexane ring with all the chloro groups in axial positions. Each carbon atom in the cyclohexane ring would have one chlorine atom attached in the upward axial position and one in the downward axial position. The resulting structure would resemble a hexagonal ring with alternating chlorine atoms pointing up and down.
