Input: Consider Input: 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.

Output: Science


Input: Consider Input: The oxidation of one of these compounds with a Jones reagent yields carboxylic acid, and they are the product of the reaction of a ketone with a Grignard reagent. Esters are formed via a reaction of carboxylic acid and this compound in a process named for Fischer. Consisting of a hydroxyl group bonded to a carbon atom, they are given the formula R-OH. For 10 points, name this class of compounds exemplified by methanol and ethanol, the latter of which is found in hand sanitizer and beer.

Output: Science
