CHM242H5 Lecture Notes - Lecture 2: Stoichiometry, Substituent, Antibonding Molecular Orbital
Document Summary
Start at the end closer to the branch point. If the 1st branch point is the same from either end, use the 2nd branch point as reference. Assign the #c (locant) to each substituent to locate its attachment point. If 2 substituents are on the same carbon = same # List the names in alphabetical order after the - (hyphen) Name a branched constituents as a compound on its own. Stereochemistry: branch of chem; studies the 3d aspects of molecules. Rotation can happen around c-c bonds in open-chain molecules. All 6 c-h bonds are as far away from e/o as possible. All 6 c-h bonds are as close to e/o as possible. Geometric arrangement around a c c single bond in which the two largest substituents are (cid:1005)8(cid:1004) apart. Conformation of butane in which the two methyl groups lie 60 apart. E maxima (eclipsed) - e minima (staggered) repulsive interaction that occurs when atoms are forced closer together.
