Q. Which one of the following is another name of RDX? (UPSC Prelims 2007)
Answer: Cyclonite
Notes: RDX (Cyclonite) is a powerful organic explosive compound with the chemical name cyclotrimethylenetrinitramine. Cyclonite is the common alternative name for RDX, widely used in military and industrial applications. The term cyclonite derives from its cyclic molecular structure combined with its nitramine functional groups. RDX was first synthesized in 1898 and has been extensively utilized in explosive formulations, propellants, and detonators due to its high detonation velocity and stability. The other options—cyanohydrin (an organic compound class), selenium (a chemical element), and cyclohexane (a saturated hydrocarbon)—are completely different substances unrelated to RDX's chemical composition or properties.
