What is the difference between axial and equatorial bonds?
The key difference between axial and equatorial position is that axial bonds are vertical while equatorial bonds are horizontal. The terms axial and equatorial are important in showing the actual 3D positioning of the chemical bonds in a chair conformation cyclohexane molecule.

Which is more stable of the axial and equatorial bonds?
Axial and equatorial are types of bonds found in the ‘chair’ conformation of cyclohexane. The chair conformation of cyclohexane has to lowest totally energy and is, therefore, the most stable.
Why are equatorial bonds more stable than axial?
Substituents prefer equatorial rather than axial positions in order to minimize the steric strain created of 1,3-diaxial interactions. The more stable conformation will place the larger substituent in the equatorial position.

Are wedges and dashes axial or equatorial?
In all cases, a substituent that was marked by a wedge or a dash in a 2-D drawing will remain that way, but in the chair conformation, the wedge might means axial “up” instead of equatorial “up” depending on whether it is a right- or left-handed chair.
Are axial bonds longer than equatorial?
The axial bonds are longer than equatorial bonds because of greater repulsion from equatorial bonds. So axial bonds are nearer to equatorial bonds and this causes greater repulsion resulting in elongation of bond length.
Which position axial or equatorial is more favorable?

What are axial bonds?
Axial: In cyclohexane, a bond which is parallel to the axis of the ring, or a group attached by such a bond. A = axial positions; E = equatorial positions. Related terms: Chair conformation, stereochemistry, axatorial, equial.
Does dash mean axial or equatorial?
Is CIS axial or equatorial?
Because of the alternating nature of equatorial and axial bonds, the opposite relationship is true for 1,3-disubstitution (cis is all equatorial, trans is equatorial/axial).
