R-114
By comparing R - (m - 1) (n + 1)p
We get,
m - 1 = 1; ⇒ m = 2
n + 1 = 1
⇒ n = 0; p = 4
2m + 2 = n + p + q
6 = 0 + 4 + q ; q = 2
Hence its chemical formula is
Also, CF2Cl-CF2Cl

Correct nomenclature for ethylene is R 150
Explanation:
The nomenclature system used for naming refrigerants is called the "Refrigerant Numbering System" or the "R-number system". This system was developed by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) and is widely used in the industry.
Refrigerant R 150:
R 150 is the correct nomenclature for ethylene. Ethylene is a hydrocarbon compound with the chemical formula C2H4. It is a colorless gas with a sweet odor and is commonly used as a refrigerant in low-temperature applications.
Significance of R-number:
The R-number assigned to a refrigerant provides important information about its chemical composition, thermodynamic properties, and environmental impact. The R-number system helps in identifying and categorizing different refrigerants based on their characteristics.
Other options:
- R 740: This nomenclature is not correct for ethylene. R 740 refers to carbon dioxide (CO2), which is another commonly used refrigerant.
- R 1150: This nomenclature is not correct for ethylene. R 1150 refers to ethane (C2H6), which is also a hydrocarbon compound but has different properties compared to ethylene.
- R 12: This nomenclature is not correct for ethylene. R 12 refers to dichlorodifluoromethane (CCl2F2), which is an ozone-depleting refrigerant commonly known as Freon-12.
Conclusion:
The correct nomenclature for ethylene is R 150. It is important to use the correct nomenclature when working with refrigerants to ensure proper identification and handling.
