Question: The Schlenk equilibrium, which can be affected by the presence of dioxane, describes the stability of these compounds, whose synthesis can be improved by the addition of mercuric chloride amalgamates. They react with nitriles to form intermediate imine anions, and dry carbon dioxide can be bubbled through them to create carboxylic acids, which themselves do not form an addition product with these. In what is sometimes called their namesake's reaction, they act as strong nucleophiles to form tertiary or secondary alcohols from ketones or aldehydes. For 10 points, name these compounds formed by reacting an alkyl halide with magnesium, named for a French guy.

Answer: Science


Question: Instead of employing the Debye-Hull-Scherrer powder method, its namesakes relied on an array of atomic planes. Its namesakes built a vacuum apparatus and employed a hot filament, an accelerating electrode, and an arc-mounted Faraday box. A leak in the vacuum led its namesakes to heat the target, resulting in crystallized nickel, which gave startling results. A plot of collector current against beam energy was explained by constructive interference, and the results in general could be derived by combining Bragg's equation with the de Broglie wavelength for electrons. FTP name this experiment named for two physicists, which proved that electrons diffract.

Answer: Science


Question: An 1889 strike of dockworkers in this city was settled at Millwall and mediated by Edward Manning. A wildly popular account of this city's underbelly was published by Ned Ward, who also described how the Mohawks and Hawkubites terrorized the women of this city. Joseph Bazalgette was largely responsible for redesigning this metropolitan area's sewer system after the Great Stink occurred. The police force of this city received the "Dear Boss" and "From Hell" letters, which enigmatically predicted a grisly set of crimes. Henry Cole organized an event in this city that displayed "the works of industry of all nations" in its Joseph Paxtondesigned structure. Its Whitechapel district was home to a series of unsolved murders. For 10 points, the Great Exhibition of 1851 took place in what city, which was also home to the Jack The Ripper killings
