What is the common characteristic of the chemical substances generally known as CL-20, HMX and LLM-105, which are sometimes talked about in media?

1. These are alternatives to hydrofluorocarbon refrigerants
2. These are explosives in military weapons
3. These are high-energy fuels for cruise missiles
4. These are fuels for rocket propulsion

Explanation

Option (b) is Correct

• CL-20 (Hexanitrohexaazaisowurtzitane), HMX (High Melting Explosive), and LLM-105 are high-energy explosives. These compounds are used in military applications due to their high detonation velocity and pressure, making them powerful and efficient in weapons like bombs and warheads.

Answer: (b) These are explosives in military weapons; Difficulty Level: Hard
