Sawhorse Structure

A pictorial representation used in chemistry to visualize the spatial arrangement of bonds and atoms in a molecule, providing a three-dimensional perspective.

Eclipsed Conformer

A conformer of a molecule in which adjacent atoms are aligned with minimal spatial separation, leading to maximal torsional strain.

Ethane

A colorless, odorless gas, which is the second simplest alkane, with the chemical formula C2H6.

Conformational Isomers

Molecules that have the same molecular formula and sequence of bonded atoms (constitution), but differ in the three-dimensional orientations of their atoms in space due to rotation around a single bond.
