JEE Mains · Chemistry · STD 11 - 4. Chemical bonding and molecular structure
According to molecular theory, the species among the following that does not exist is
- A \(He _{2}^{+}\)
- B \(He _{2}^{-}\)
- C \(Be _{2}\)
- D \(O _{2}^{2-}\)
Answer & Solution
Correct Answer
(C) \(Be _{2}\)
Step-by-step Solution
Detailed explanation
Chemical Species Bond Order \(He _{2}^{+}\) \(0.5\) \(He _{2}^{-}\) \(0.5\) \(Be _{2}\) \(0\) \(O _{2}^{2-}\) \(1\) According to \(M.O.T.\) If bond order of chemical species is zero then that chemical species does not exist.
