CH4 is called methane and it exists as a gas at room temperature and pressure
H2S is hydrogen sulfide, which is a smelly gas with a rotten egg smell
CCl2F2 is dichloro difluoro methane. It is a gas commonly used in refrigeration. It becomes a liquid under pressure.

CH4 is methane,
H2S is hydrogen sulfide,
I dont know what the third one is but i will look it up.
CCl2F2 is Dichlorodifluoromethane
BTW I disagree with the above answer number two, Hyrdogen sulfide is correct
