Definitions:

Molecular Dipole

A measure of the overall polarity of a molecule, arising from the vector sum of all individual bond dipoles or the separation of positive and negative charges within a molecule.

Chair Conformation

A three-dimensional geometric shape of cyclohexane that significantly reduces angular and torsional strain, making it more stable than other conformations.

Trans-Decalin

A specific configuration of decalin (a bicyclic compound) where the hydrogen atoms at the bridgehead positions are on opposite sides.

Stable Conformation

Stable conformation describes the most energetically favorable spatial arrangement of atoms in a molecule, minimizing strain and maximizing stability.
