The refrigerant -12 (R – 12) used in vapour compression refrigeration...
For Cm Hn CIq Fp
n + p + q = 2m + 2,
formula is R(m – 1) (n + 1) p
P = 2, No hydrogen atom, n = 0
∴ q = 2 × 1 + 2 = 4
∴ Designation for R – 12 is CCI2 F2

The refrigerant -12 (R – 12) used in vapour compression refrigeration...
Explanation:
Chemical Formula:
- The refrigerant R-12 used in vapor compression refrigeration systems has a chemical formula CCl2F2.
Properties:
- R-12 is a colorless gas with a faint ethereal odor.
- It is non-flammable and non-explosive, making it a safe choice for refrigeration systems.
Environmental Impact:
- Despite its effectiveness as a refrigerant, R-12 is known to contribute to ozone depletion.
- Due to its harmful effects on the environment, the use of R-12 has been phased out in many countries.
Replacement:
- In response to environmental concerns, R-12 has been replaced by more environmentally friendly refrigerants such as R-134a and R-410a.
Conclusion:
- The correct chemical formula for the refrigerant R-12 used in vapor compression refrigeration systems is CCl2F2. While it was once widely used, its negative impact on the environment has led to its replacement with more eco-friendly alternatives.
