Q: These compounds are described using the  E-Z [E dash Z] notation when they occur across alkenes, and a more generalized version of that notation is the cis-trans notation. Both of those are examples of diastereomers [di-uh-stereo-mers], and examples of these include cyclohexane and hexene. Differing bonding patterns make up structural ones of these compounds. When these compounds are mirror images of each other, they are referred to as enantiomers [en-anti-omers]. For 10 points, name these compounds that have varying chemical structures despite having the same chemical formula.

Q: One reactant for this reaction is best prepared by an S N 2 nucleophilic addition of a triphenyl compound, followed by elimination of the hydrogen halide by an organolithium reagent. This reaction itself proceeds through a rather unique intermediate formed when the pi electron from the reagents carbon-oxygen double bond migrates to the positively charged pole of one reactant; this intermediate is called a an oxaphosphetane, from which a triphenyl oxide is eliminated to complete the reaction. The aforementioned positively charged pole is on phosphorous because the aforementioned prepared reactant is a phosphorous ylide. For ten points, name this reaction that produces selectively double-bonded alkenes from aldehydes and phosphorous ylides and that is named for the German 1979 Chemistry Nobel winner.

Q: The life of Ferdinand Laysalle inspired this authors novel about Alvan and Julia, The Tragic Comedians. One of this mans poems ends, we drop like the fruits of the tree, / Even we, / Even so; another ends with the image of The army of unalterable law. In addition to Dirge in Woods and Lucifer in Starlight, he wrote By this he knew she wept with waking eyes as the first of 50 16-line sonnets chronicling a failed relationship. One of his novels sees the title character elope with Lucy Desborough, and another sees the title character marry Laetitia Dale after losing the love of Clara Middleton. It was his unhappy first marriage that inspired his sonnet sequence Modern Love. FTP, name this author of The Ordeal of Richard Feverel who wrote about Sir Willoughby Patterne in The Egoist.
