Answer:

C. Royal Demolition Explosives

Understanding RDX: A Detailed Explanation

• RDX stands for Royal Demolition Explosive, also known as Research Department Explosive, reflecting its origins and purpose.
• Its chemical name is Cyclotrimethylenetrinitramine or Hexogen.
• RDX is a powerful nitramine class explosive, widely used in military and demolition applications.
• It is a white, crystalline solid, relatively stable and non-hygroscopic, making it suitable for long-term storage and use in various environmental conditions.

• Historical Context:

  • RDX was first synthesized in 1898 by the German chemist Georg Friedrich Henning.
  • However, its explosive properties were not fully recognized or utilized until the early 1940s during World War II, when it was developed independently by the British and American research departments.
  • The name 'Royal Demolition Explosive' was given by the British.

• Applications and Characteristics:

  • RDX is one of the most powerful and versatile conventional explosives. Its velocity of detonation is very high, typically around 8,750 meters per second (28,700 ft/s).
  • It is often used as the main explosive in plastic explosives like C4 (Composition C4), where it is combined with plasticizers, binders, and other materials to make it moldable and stable.
  • It is also a key component in other military explosives and propellants, including some types of artillery shells, grenades, and rocket propellants.
  • Due to its high stability and brisance (shattering power), RDX is preferred for military applications over some other explosives.
  • It is less sensitive to shock and friction than primary explosives like mercury fulminate, but still requires careful handling.
