CCl₄

Back

carbon tetrachloride

Answer explanation

CCl4 is the chemical formula for carbon tetrachloride, which consists of one carbon atom and four chlorine atoms. The correct option is 'carbon tetrachloride' as it accurately represents the given chemical formula. The other options, such as methane, carbon quadchloride, and monocarbon tetrachloride, do not correspond to the CCl4 formula.

NF₃

Back

nitrogen trifluoride

Answer explanation

The correct answer is nitrogen trifluoride. NF3 represents a chemical compound with one nitrogen atom (N) and three fluorine atoms (F). The prefix 'mono' is not needed for the first element in a compound, so 'mononitrogen trifluoride' and 'mononitrogen trifluorine' are incorrect. Ammonia is a different compound with the formula NH3.
