PROBLEM: When reacted with a nitrile, they produce an imine anion that can be hydrolyzed into a ketone, and they can cause nucleophilic ring opening of epoxides. Pouring a solution of them over dry ice followed by protonation results in carboxylic acids, which will not form addition products with these. One of their most common uses is reacting with aldehydes and ketones to form secondary and tertiary alcohols, respectively. Because they essentially act as carbanions, they can be protonated by weak acids to yield alkanes. FTP name these organometallic reagents that are formed by reacting an alkyl halide with magnesium, named for their French discoverer.

SOLUTION: Science

PROBLEM: One of his works argues that rationality is the core of all reality, and states that there is no reality besides that which is shaped by the mind; a condensed version of this work can be found in his Encyclopedia of the Philosophical Sciences. One of his works divides the title concept into abstract, moral and ethical spheres, and posits the idea that free will can only be realized in systems of property rights and contracts. In addition to the aforementioned Science of Logic, another work relies on the thesis-antithesis-synthesis method, and includes discussions of Absolute Knowing and the master-slave dialectic. FTP, name this German philosopher and author of The Philosophy of Right and Phenomenology of Mind.

SOLUTION: Social Science

PROBLEM: He left the novel Answered Prayers incomplete at his death, and his last finished work was the novel Music for Chameleons. The two most important themes in his works were homosexuality and the lost child, as demonstrated by his collections A Tree of Night and Other Stories and One Christmas. However, he is better remembered for the journalistic style of his longer fiction works, such as The Grass Harp and The Thanksgiving Visitor.
