Question 1 of 27070

Monochlorodifluoromethane (R-22) when vaporized in the presence of an open flame, will form what chemical substance?

🔍 Key Concepts

• Refrigerant R-22 (monochlorodifluoromethane) thermal decomposition products • How halogenated hydrocarbons (chlorine-containing compounds) behave in a high-heat/open-flame environment • Typical toxic gases associated with burning refrigerants and plastics

💭 Think About

• When a chlorine-containing refrigerant is exposed to very high heat or flame, what toxic gas is historically associated with war gases and also with combustion of some plastics and solvents? • Look at each option and ask: which one is well-known as a highly toxic gas formed when certain chlorinated compounds burn? • Which choice is specifically linked in safety training to the danger of heating or burning refrigerants in enclosed spaces?

✅ Before You Answer

• Verify which option is a highly toxic decomposition product of chlorinated hydrocarbons under flame, rather than a normal combustion product like CO₂. • Recall which gas among the options has a strong historical association with chemical warfare and severe lung injury. • Eliminate any options that are not typically produced from burning chlorine-containing refrigerants (think about which contain sulfur or different halogens).
