Ex Input:
The elimination mechanism by which the dehydration of its major product occurs necessarily involves the abstraction of an acidic hydrogen and displacement of the leaving group. The catalyst in this reaction itself is regenerated from the deprotonation of water in its final step, which results in the conversion of its intermediate, an alkoxide. An aldehyde or ketone had originally undergone a nucleophilic-addition-type process to produce that alkoxide, which had converted it from a nucleophilic enolate using a hydroxide ion catalyst. Producing a final product known as a beta-hydroxyaldehyde, FTP, name this condensation reaction whose name combines that of its two final products.

Ex Input:
LDA is used to transform propargyl diol into one of these compounds in the Whiting reaction. A useful one of these compounds is synthesized using zinc chloride to combine trimethylsilyl chloride with methoxybutenone. The namesake value of these compounds is expressed as the mass of iodine equivalent to the amount of (*) maleic anhydride reacting with a unit mass of one of these. The cumulated type of these compounds are less stable than other types. Electrophilic addition can result in both 1,2 and 1,4 additions in the conjugated type of these molecules. That type also undergoes a type of reaction that follows the endo addition rule and forms cyclohexenes, the Diels-Alder reaction. For 10 points, name these hydrocarbons that contain two carbon-carbon double bonds.

Painted in Dusseldorf in 1851, this work was such an immediate success that it brought its German-born American artist a commission to paint a mural for the United States Capitol, which culminated in 1860's Westward the Course of Empire Takes its Way. Land can be seen on the left, and a man struggles with an ice floe, while other boats are visible in the right background. Identify this painting by Emanuel Leutze, whose title figure assumes a determined stance in a portrayal of, FTP, an event from Christmas Eve of 1776.
