Nucleophilic substitution reactions VII. Substitutions: The SN2 reaction Current Lecture I. Gargantulide A Biggest organic molecule, composed of a 52 carbon ring Naturally occurring Very powerful antibiotic, but also very poisonous More than half of the carbons are chiral II. Organohalides Organic compound containing at least one carbon-halogen bond (C-X), normally contains several Fire resistant solvents (don’t ever burn), inert, stable Refrigerants Used in pharmaceuticals (Cl, Br, F) & precursors Splenda – substitute in Cl Body doesn’t recognize it as a sugar and so doesn’t digest it Retains some of the basic properties (i.e. sweetness) III. Naming Alkyl Halides Triple bond needs to be in the parent chain Number from end nearest any substituent (halogen or alkyl – neither have priority) If two halides or alkyls are equally distant from the ends of the chain, work alphabetically i.e. 2-bromo-5-methylhexane These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.
