Question

What are Freons?

Answer 1

The chloro fluoro derivatives of methane and ethane are called freons.

Freon is represented as Freon – cba

Where, c = number of carbon atoms, b = number of hydrogen atoms, a = total number of fluorine atoms.

CF₂Cl₂ = 0

c = 1 – 1 = 0

H = 0 +1 = 1

F = 2

So Freon – 12 is CF₂Cl₂
