Chapter 7 Important Concepts 5. Unimolecular elimination to form an alkene accompanies substitution in secondary and tertiary systems. 6. High concentrations of strong base may bring about bimolecular elimination . Expulsion of the leaving group accompanies removal of a hydrogen from the neighboring carbon by the base. The stereochemistry indicates an anti conformational arrangement of the hydrogen and the leaving group. 7. Substitution is favored by unhindered substrates and small, less basic nucleophiles. 8. Elimination is favored by hindered substrates and bulky, more basic nuccleophiles. Chapter 8 Important Concepts 1. Alcohols are alkanols in IUPAC nomenclature. The stem containing the functional group gives the alcohol its name. Alkyl and halo substituents are added as prefixes. 2. Like water, alcohols have a polarized and short O-H bond. The hydroxyl group is hydrophilic and enters into hydrogen bonding . Consequently, alcohols have unusually high boiling points and, in many cases, appreciable water solubility. The alkyl part of the molecule is hydrophobic . 3. Again like water, alcohols are
