The correct formula-name combination is:<\/p>\n\n\n\n
Chlorine monoxide: ClO<\/strong><\/p>\n\n\n\n When naming chemical compounds, especially those involving nonmetals like chlorine and oxygen, the rules of nomenclature for molecular compounds<\/strong> apply. These rules use prefixes to indicate the number of atoms of each element in the compound. Let\u2019s examine each combination to identify the correct one.<\/p>\n\n\n\n Therefore, among the options given, “Chlorine monoxide: ClO”<\/strong> is the only correct formula-name match based on modern chemical nomenclature rules. Understanding and applying these rules ensures consistency and accuracy in chemical communication.<\/p>\n\n\n\n Which formula-name combination is correct? Chlorite: ClO2 Dichlorine pentoxide: Cl2O7 Dichlorine heptoxide: Cl2O6 Chlorine monoxide: ClO Dichloride oxide: Cl2O The Correct Answer and Explanation is: The correct formula-name combination is: Chlorine monoxide: ClO Explanation When naming chemical compounds, especially those involving nonmetals like chlorine and oxygen, the rules of nomenclature for molecular compounds apply.

Incorrect. “Chlorite” refers to a polyatomic ion<\/strong> with the formula ClO\u2082\u207b, not a neutral compound. It carries a negative charge and is typically found in salts like sodium chlorite (NaClO\u2082).<\/li>\n\n\n\n
Incorrect. The name “dichlorine pentoxide” means 2 chlorine atoms and 5 oxygen atoms. However, Cl\u2082O\u2087 contains seven<\/strong> oxygen atoms. The correct name for Cl\u2082O\u2087 is dichlorine heptoxide<\/strong>.<\/li>\n\n\n\n
Incorrect. The formula Cl\u2082O\u2086 has 6 oxygen atoms. Therefore, the correct name should be dichlorine hexoxide<\/strong>. \u201cHeptoxide\u201d refers to seven oxygen atoms, which belongs to Cl\u2082O\u2087.<\/li>\n\n\n\n
Correct.<\/strong> The prefix “mono-” indicates one oxygen atom, and since there is only one chlorine atom, no prefix is needed for chlorine. Hence, ClO is correctly named chlorine monoxide<\/strong>.<\/li>\n\n\n\n
Incorrect. This is an outdated or ambiguous naming style. The modern IUPAC name uses prefixes for both elements. Cl\u2082O consists of two chlorine atoms and one oxygen atom, so the correct name is dichlorine monoxide<\/strong>.<\/li>\n<\/ol>\n\n\n\n![\"\"](\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-650.jpeg\")
