Final answer:
The combining form 'Chlor O' usually pertains to chemical compounds containing chlorine, often in relation with oxygen as in oxyanions. It involves the use of prefixes like 'tetra-' for indicating the number of chlorine atoms in carbon tetrachloride and 'per-' or 'hypo-' for oxyanions depending on the number of oxygen atoms attached.
Step-by-step explanation:
The combining form Chlor O refers to the presence of chlorine within a chemical compound, often in the context of oxyanions where chlorine is combined with oxygen. When naming compounds, such as CCl4, the name starts with the first element, carbon, followed by the modified name of the second element, chlorine, which becomes chloride. The prefix "tetra-" is added to indicate the presence of four chlorine atoms, resulting in the name carbon tetrachloride.
In the process of naming oxyanions of halogens like chlorine, specific prefixes and suffixes are used based on the number of oxygen atoms attached. For example, an ion with one more oxygen than the -ate ion uses the prefix "per-" (as in perchlorate, ClO4-), while an ion with one less uses the prefix "hypo-" and a -ous ending (as in hypochlorous acid, HClO).
Chemical reactions involving chlorine can lead to various products such as harmless compounds like sodium chloride (table salt) or different types of oxyanions, depending on the conditions of the reaction. In disproportionation reactions, chlorine can be both oxidized and reduced, forming compounds such as chloride ions, Cl-, and chlorate ions, ClO3-.
