Hypergolic materials ignite when they

• A. Contact air
• B. Contact each other
• C. Contact water
• D. Contact metal

Answer: (B)

Hypergolic materials ignite spontaneously when the fuel and oxidizer come into contact with each other. This immediate ignition happens because the two reactive components trigger a rapid chemical reaction without any external ignition source. That’s why these substances must be kept separate and only brought together in controlled systems; accidental mixing can cause immediate ignition. They don’t ignite simply by touching air, water, or metal, so those factors aren’t the trigger in hypergolics.
