Answer :
Final answer:
Organomagnesium halides (RMgX) are known as Grignard reagents, crucial tools in synthetic chemistry for creating a wide range of organic compounds. These compounds were discovered by Victor Grignard, who received a Nobel Prize for this work.The right answer is option (a) Grignard reagents
Explanation:
Organomagnesium halides, denoted as RMgX, are commonly known as Grignard reagents. These compounds are prepared via the reaction of an alkyl or aryl halide with magnesium. Discovered by Victor Grignard in the early 20th century, Grignard reagents have become indispensable tools in synthetic chemistry for creating a wide array of organic compounds. Grignard was awarded the Nobel Prize in 1912 for this significant contribution to the field of organic chemistry.
In contrast, organolithium reagents are derived from the reaction of lithium with an organohalide, and lithium diorganocopper reagents, also known as Gilman reagents, are produced from the reaction of organolithium reagents with cuprous iodide. These reagents, each possessing unique reactivities, are pivotal in various organic transformations, highlighting the diverse applications of organometallic chemistry in synthesizing complex molecules.
