The correct Answer is:
To solve the question regarding the presence of the X-O-X bond in the given species, we will analyze each compound step by step. ### Step 1: Understanding the Compounds We have four species to analyze: 1. Cl2O7 2. H2N2O7 3. N2O5 4. H2S2O7 ### Step 2: Analyzing Cl2O7 - **Structure**: Cl2O7 (Dichlorine heptoxide) consists of two chlorine atoms and seven oxygen atoms. - **Bonding**: The structure features a bridging oxygen atom between the two chlorine atoms, resulting in a Cl-O-Cl bond. - **Conclusion**: Cl2O7 has an X-O-X bond (Cl-O-Cl). ### Step 3: Analyzing H2N2O7 - **Structure**: H2N2O7 (Dinitramic acid) is derived from the combination of HNO3 and HNO4. - **Bonding**: The structure does not contain an N-O-N bond; instead, it features nitrogen atoms bonded to oxygen atoms without forming a direct N-O-N linkage. - **Conclusion**: H2N2O7 does not have an X-O-X bond. ### Step 4: Analyzing N2O5 - **Structure**: N2O5 (Dinitrogen pentoxide) consists of two nitrogen atoms and five oxygen atoms. - **Bonding**: The nitrogen atoms form bonds with oxygen, and there is a bridging structure that leads to an N-O-N bond. - **Conclusion**: N2O5 has an X-O-X bond (N-O-N). ### Step 5: Analyzing H2S2O7 - **Structure**: H2S2O7 (Pyrosulfuric acid) includes two sulfur atoms and seven oxygen atoms. - **Bonding**: The sulfur atoms are connected by an S-O-S bond, indicating a bridging structure. - **Conclusion**: H2S2O7 has an X-O-X bond (S-O-S). ### Final Conclusion From the analysis: - Cl2O7 has an X-O-X bond. - H2N2O7 does not have an X-O-X bond. - N2O5 has an X-O-X bond. - H2S2O7 has an X-O-X bond. Thus, the species that does not have the X-O-X bond is **H2N2O7**.

Oxidation number is the charge which an atom of an element has in its ion or appears to have when present in the combined state. It is also called oxidation state. Oxidation number of any atom in the elementary state is zero. Oxidation number of a monoatomic ion is equal to the charge on it. In compounds of metals with non metals, metals have positive oxidation number while non metals have negative oxidation numbers. In compounds of two difference elements, the more electronegative element has negative oxidation number whereas the other has positive oxidation number. In complex ions, the sum of the oxidation number of all the atoms is equal to the charge on the ion. If a compound contains two or more atoms of the same element, they may have same or different oxidation states according as their chemical bonding is same or different. The oxidation state of the most electronegative element in the products of the reaction between BaO_(2) and H_(2)SO_(4) are
