Chemistry - STEREO ISOMERISM Question with Solution | TestHub

In the chair shown, all axial positions carry D and all equatorial positions carry H :

The six vertical bonds, pointing alternately up and down around the ring, are the axial bonds. The six slanted bonds, each roughly parallel to the next-but-one ring bond, are the equatorial bonds. So there are 6 axial bonds (3 up, 3 down) and 6 equatorial bonds, one of each kind on every ring carbon.
