अवधारणा:

एक प्रशीतक का सामान्य रासायनिक सूत्र CmHnFpClq है

और प्रशीतक के रूप में प्रतिनिधित्व करने के लिए संकेत

R - (m - 1)(n + 1)p

और n + p + q = 2 m + 2

गणना:

दिया हुआ:

शीतलक R - 22 = R - 022 

जैसा कि हम जानते हैं,R - (m - 1)(n + 1)p

m - 1 = 0 ⇒ m = 1

n + 1 = 2 ⇒ n = 1

p = 2 ∴ q = 1

∴ CmHnFpClq = CHClF2
