Question

Elaidic (“EL-ay-id-ick”) acid undergoes this reaction to form stearic acid. A catalyst commonly used for this reaction consists of three triphenylphosphine (“tri-FEN-ill-FOSS-fene”) groups bonded to a rhodium atom and is named for Wilkinson. This reaction (-5[1])is performed in a “syn-” (“sin”) fashion on a palladium or platinum (-5[1])catalyst. Due to isomerization, this reaction may introduce trans byproducts while making products less prone to auto-oxidation (-5[1])and more solid (10[1])at room temperature. This type of addition reaction is used to produce margarine by reducing alkenes (10[1])to saturated alkanes. (10[1])For 10 points, name this reaction in which a molecule gains two atoms (-5[1])of the lightest element. ■END■ (10[8]0[5])

ANSWER: hydrogenation [accept hydrogenization; accept word forms like hydrogenate; accept fat hydrogenation or hydrogenated oils or hydrogenated fats; accept partial hydrogenation; accept hydrogen addition; prompt on addition until read; prompt on reduction or redox reactions or word forms like reducing until “reducing” is read; reject “dehydrogenation”] (The third line refers to trans fats.)
