The equatorial conformation is more stable in a cyclohexane chair conformation.
The equatorial orientation is more stable in terms of energy for a substituent in a cyclohexane chair conformation.
The boat conformation of cyclohexane is significant because it allows for the positioning of axial and equatorial substituents in a way that minimizes steric hindrance. Axial substituents are positioned vertically, while equatorial substituents are positioned horizontally, reducing the strain on the molecule and increasing stability.
In a molecule, the equatorial position is generally more stable than the axial position.
The equatorial region is more stable than the axial region because it receives more consistent sunlight and heat throughout the year, leading to a more balanced climate and fewer extreme temperature fluctuations.
The axial bond is 158 pm and the equatorial is 152 pm. One explanation is that the hybridisation of the equatorial bonds is sp2 and the hybridisation of the equatorial is pd, the greater s character of the equatorial making the bond shorter. (taken from text book Inorganic chemistry by House) I know of no theretical study that backs this up. Most text books duck this ,e.g Greenwood and Wiberg.

The most stable conformation of cyclohexane is the chair conformation. In this conformation, all carbon atoms are in a staggered position and there is minimal steric hindrance between the hydrogen atoms. This results in the lowest energy state for the molecule.
Polar groups prefer the axial position in cyclohexane because it minimizes steric hindrance with neighboring atoms, allowing for better overlap of orbitals and stabilizing the molecule. In the axial position, the polar group experiences less repulsion from other groups compared to being in the equatorial position, which leads to a more energetically favorable conformation.
In a molecule, the equatorial position is generally more stable than the axial position.
The most stable conformation has the larger bromine atom in the equatorial position to reduce steric hindrance caused by its size. Placing the smaller chlorine atom in the axial position minimizes the overall energy of the molecule due to the difference in size between bromine and chlorine. This arrangement follows the principles of minimizing steric hindrance and maximizing stability.
The equatorial region is more stable than the axial region because it receives more consistent sunlight and heat throughout the year, leading to a more balanced climate and fewer extreme temperature fluctuations.
Chair form (of hexane) is more stable configuration because out of eight hydrogen four form the equatorial bonds and four axial bonds so its a symmetrical structure and repulsive force among the hydrogens is minimum.
axial bonds are longer than equatorial bonds becz axial bond contain very less "s" character as compare to equatorial bond, hence probability of finding it near nucleus is less hence force of attraction by nucleus is less as compare to to equatorial bonds

In PCl5, the two chlorine atoms that are more reactive are located in the axial positions, while the three equatorial chlorine atoms are in a more stable, sterically hindered arrangement. The axial chlorine atoms experience greater repulsion from the equatorial chlorines and are less shielded, making them more susceptible to reacting with other species. Additionally, the axial positions allow for better overlap with potential reactants, further enhancing their reactivity compared to the equatorial chlorines.
The bond angle formed by an axial atom, the central atom, and an equatorial atom in a trigonal bipyramidal molecular geometry is approximately 90 degrees.
