Which of the following statements is/are true? This question has multiple correct options

1. It is impossible to satisfy the octet rule for all atoms in \( X e F_{2} \)
2. \( M g S O_{4} \) is soluble in water because hydration energy of \( M g S O_{4} \) is higher in comparison to its lattice energy.
3. The bond in \( N O^{+} \) should be stronger than the bond in \( N O^{-} \)
4. For ozone molecule, one oxygen-oxygen bond is stronger than the other oxygen-oxygen bond.

Correct answer: The bond in \( N O^{+} \) should be stronger than the bond in \( N O^{-} \)

Solution

In NO⁺, one electron is removed relative to NO, increasing bond order and strengthening the N–O bond. In NO⁻, an extra electron enters an antibonding orbital, lowering bond order and weakening the bond.
