# What is the molecule obtained when methane is substituted by two fluorine, and one chlorine atom?

$C H {F}_{2} C l$
Well methane is $C {H}_{4}$, replace a hydrogen by fluorine we get $\text{fluoromethane}$, $C {H}_{3} F$, replace another hydrogen by fluorine we get $\text{difluoromethane}$, $C {H}_{2} {F}_{2}$, replace another hydrogen by chlorine we get $\text{chlorodifluoromethane}$, $C H C l {F}_{2}$. Due to its potential for global warming, this is the molecule that is being phased out....
