(crowding) Strain on a molecule when 2 groups are too close and try to occupy the same space.

Atom or group of atoms substituted in place of an H atom on the parent Hydrocarbon chain.

Strain in a molecule caused by electron repulsion between eclipse bonds.

Bond to a chair-cylcohexane that lies along the rings axis perpendicular to the plane of the ring.

• Conformation of cyclohexane that resembles a boat.
• (less stable than chair due to eclipse interactions)

• Conformation of cyclohexane that resembles a chair,
• (more stable than, lowest energy conformation)
