Document Summary
Substituents are alkyl groups, halogen, or alkoxy groups. Functional groups always have priority over substituents (given 1st position). If only one substituent or functional group is attached to a ring carbon, no numerical locant is required. If two or more substituents are attached to ring, both must have numerical locants with the highest priority assigned #1. 2: put in descending order in brackets. Ignoring bridgehead carbons, count carbon bridges is the amount of energy gained or lost enthalpy of activation, energy barrier between reactant and product. Substituents count starting at bridgehead to largest bridge to smaller bridges in sequence. Rings have a semi-rigid structures that do not allow free rotation around c-c bonds. Orientation of axial and equatorial alternates around ring. Axial and equatorial off the same carbon point in opposite directions, one up, the other down. The axial always points in same direction as carbon relative to ring. A measure of the energy content of a system or substance.
