Guys, passing an aptitude test doesnt mean ur the most intelligent. I knw people that scored almost more than twice my score during an aptitude test. They were boastn. But we met at an assessment centre where u will work in a team and also work alone to present the topic they gv u as a seminar, many of those guys failed! I was among the few that were offered the job! In that apt test, my score was just 45 and the ppl i met at the assessment centre scored upto 75! Its nt always gd to boast! Intelligent guys dnt make noise or brag or look down on others. I hv written a coca cola test where thousands of ppl participated includn some guys i knw that got 1st class in my sch. After the test, they met me and was telln me they even saw the questions before we wrote. But could u believe that none of them made it to the next stage. I was among the few that still made it to the last stage. Please lets learn hw to respect each other. I still knw my mates that got 2nd class upper but cant write an application letter.

The first refrigerators built from the 1800’s until the 1920’s primarily used toxic gases such as ammonia (NH3), methyl chloride (CH3Cl), and sulfur dioxide (SO2). Unfortunately, the units occasionally leaked and caused several deaths, which prompted the refrigeration industry to put forth a concerted effort to find a safer refrigerant gas. The result was the discovery of chlorofluorocarbon (CFC) gas, which was a mixture of chlorine, fluorine and carbons. Freon® became the trademark name for a CFC gas that was primarily used as a refrigerant. This gas was colorless, odorless, nonflammable and non-toxic, and soon became the predominant gas used as a refrigerant.

Unfortunately, scoffield was right afterall. The answer is actually[b] freon[/b]. SO2 was used in the past.

Ugo Kingsley, A.K.A Scoffied, you reek of crass indiscipline and you epitomize fatuousness , you are a raving bonker cruising on a first class flight to hades, your nerdy-like attitude depicts you as a cockamamie, your cerebral dwarfism is amazing, too dreary and conterminous to intellectual bankruptcy.
i wont exchange vitriolic with a chimera. But down to the basics since you said your objective is to create a platform for learning.

Your answer on "which of these is a refrigerant ... ?' is wrong, it is not Freon, but Sulfur dioxide.

Freon is the trade name of DuPont which produces and packages non-halogenated hydrocarbons refrigerant, types of refrigerant includes ammonia, sulfur dioxide, and non-halogenated hydrocarbons such as propane.

Its just like asking, which of these is not a building material (1) blocks (2) cement (3) nails (4) Dangote. and you decide to pick (4) Dangote, because there is dangote cement then you are wrong, dangote is a trade name of a company that produces cement.

If you were to be in United States, you will be tied to the stakes and shot on the chest for low intelligence. I still insist that you are not likely to score above 40%, anything other than that is fraud.

you dont seem to understand the question. The question is not on which refrigerant is safe

Freon is a trademark

Sulfur dioxide is the refrigerant as contained in the question
