The common name for dichlorodifluoromethane is Freon-12.
CCl2 does exist as a reactive intermediate (but fleetingly and not stable) and is known as Dichlorocarbene. It is available in singlet and triplet format. However, CCl4 is stable and is known as tetrachloromethane or carbon tetrochloride.
Dichlorodifluoromethane has 3 different elements: carbon, chlorine, and fluorine.
CF2Cl2
The name of CF2Cl2 is dichlorodifluoromethane.
C2Cl6 (dichlorodifluoromethane) is a nonpolar molecule due to its symmetrical tetrahedral shape and the equal sharing of electrons between carbon and chlorine atoms. This results in no overall dipole moment, making it nonpolar.
CCl2F2, also known as carbon tetrachloride, is a nonpolar molecule. This is because the electronegativity difference between carbon and chlorine/fluorine atoms is very small, resulting in a symmetrical distribution of electrons around the molecule, making it nonpolar.
The chemical equation for the ozone depletion by dichlorodifluoromethane (CFC-12) can be described as: CF2Cl2 + UV light → CF2Cl· + Cl· Cl· + O3 → ClO· + O2 ClO· + O· → Cl· + O2 Overall: O3 + O· → 2O2
Dichlorodifluoromethane ("Freon") has a boiling point of -21.6o F (-29.8o C).
A common name for CF2Cl2 is dichlorodifluoromethane, which is also commonly known as CFC-12.
Gas used in air conditioners are: R12 freon is dichlorodifluoromethane R134a is Tetrafluoroethane
The freezing point of R-12 ( Dichlorodifluoromethane, a form of Freon) is −157.7 °C.
