WebCarbon four is straight down for an axial hydrogen. Carbon five back here would be up, and then, carbon six would be, would be down axial hydrogen. So you can see that we alternate. If we start at carbon one, we start up axial, so let's go ahead and put in the axial hydrogens on our Cyclohexane, on our chair conformation. So here is carbon one.
