Document Summary

Example: bicycle [2. 2. 1] heptane: if substituent is present, name the main chain first to properly assign a number. Assign the substituents the lowest number, but must have the proper number for main chain first (going the longest path). Name substituents before main chain: to name the main chain, name it starting from the longest carbon path first. Start at the bridgehead carbons to assign a number: the carbons that connect the two shapes are the ones that forms the bridgehead, when naming parent chain, count the carbons on the bridgeheads too, also arrange alphabetically. 1) draw the newman projection as viewed from the angle indicated. 3) draw the skeleton of a newman projection (the circle) then determine the direction of each molecule and correctly label on the projection. Take into account the wedges and dashes of a molecule and whether it is pointing away or towards you: from least to most stable is eclipse, gauche, and staggered conformation.
