The correct Answer is:
To determine which diatomic molecules or ions have the same bond order, we need to analyze the total number of electrons in each species. The bond order can be calculated based on the number of bonding and antibonding electrons, but for this question, we can simplify our approach by counting the total number of valence electrons. ### Step-by-Step Solution: 1. **Identify the total number of electrons in each molecule/ion.** - **O2 (Oxygen molecule):** - Each oxygen atom has 6 valence electrons. - Total for O2 = 2 × 6 = 12 electrons. 2. **Calculate the total number of electrons for CN- (Cyanide ion):** - Carbon has 4 valence electrons and nitrogen has 5 valence electrons. - Total for CN- = 4 (from C) + 5 (from N) + 1 (extra electron due to negative charge) = 10 electrons. 3. **Calculate the total number of electrons for N2 (Nitrogen molecule):** - Each nitrogen atom has 5 valence electrons. - Total for N2 = 2 × 5 = 10 electrons. 4. **Calculate the total number of electrons for C2 (Carbon molecule):** - Each carbon atom has 4 valence electrons. - Total for C2 = 2 × 4 = 8 electrons. 5. **Summarize the total number of electrons:** - O2: 12 electrons - CN-: 10 electrons - N2: 10 electrons - C2: 8 electrons 6. **Identify which species have the same number of electrons:** - CN- and N2 both have 10 electrons. 7. **Conclusion:** - Since CN- and N2 have the same number of electrons, they will have the same bond order. ### Final Answer: The diatomic molecules/ions that have the same bond order are **CN- and N2**. ---

    In which of the following pair, the two molecules have identical bond orders :

    MO' s are formed by the overlap of A'O s Two AO's combine to form two MO's called bonding molecular orbital (BMO) and antibonding molecular orbital (ABMO) Differnet AO' s of one atom combine with these AO 's of the second atom which have comparable energies and proper orienation Further, If the overlapping is head on, the MO is called 'pi' The MO's are filled with electrons following the same rules as followed for filling of atomic orbitals However the order of filling is not the same for all molecules or their ions Bond order is one of the most important parameter to compare a number of their characteristics Which of the following has pair is expected to have the same bond order ? .
